Primitive Type slice [−]
A dynamically-sized view into a contiguous sequence, [T].
Slices are a view into a block of memory represented as a pointer and a length.
fn main() { // slicing a Vec let vec = vec![1, 2, 3]; let int_slice = &vec[..]; // coercing an array to a slice let str_slice: &[&str] = &["one", "two", "three"]; }// slicing a Vec let vec = vec![1, 2, 3]; let int_slice = &vec[..]; // coercing an array to a slice let str_slice: &[&str] = &["one", "two", "three"];
Slices are either mutable or shared. The shared slice type is &[T],
while the mutable slice type is &mut [T], where T represents the element
type. For example, you can mutate the block of memory that a mutable slice
points to:
let x = &mut [1, 2, 3]; x[1] = 7; assert_eq!(x, &[1, 7, 3]);
Methods
impl<T> [T]
Allocating extension methods for slices.
fn len(&self) -> usize
Returns the number of elements in the slice.
Example
fn main() { let a = [1, 2, 3]; assert_eq!(a.len(), 3); }let a = [1, 2, 3]; assert_eq!(a.len(), 3);
fn is_empty(&self) -> bool
Returns true if the slice has a length of 0
Example
fn main() { let a = [1, 2, 3]; assert!(!a.is_empty()); }let a = [1, 2, 3]; assert!(!a.is_empty());
fn first(&self) -> Option<&T>
Returns the first element of a slice, or None if it is empty.
Examples
fn main() { let v = [10, 40, 30]; assert_eq!(Some(&10), v.first()); let w: &[i32] = &[]; assert_eq!(None, w.first()); }let v = [10, 40, 30]; assert_eq!(Some(&10), v.first()); let w: &[i32] = &[]; assert_eq!(None, w.first());
fn first_mut(&mut self) -> Option<&mut T>
Returns a mutable pointer to the first element of a slice, or None if it is empty
fn split_first(&self) -> Option<(&T, &[T])>
Returns the first and all the rest of the elements of a slice.
fn split_first_mut(&mut self) -> Option<(&mut T, &mut [T])>
Returns the first and all the rest of the elements of a slice.
fn split_last(&self) -> Option<(&T, &[T])>
Returns the last and all the rest of the elements of a slice.
fn split_last_mut(&mut self) -> Option<(&mut T, &mut [T])>
Returns the last and all the rest of the elements of a slice.
fn last(&self) -> Option<&T>
Returns the last element of a slice, or None if it is empty.
Examples
fn main() { let v = [10, 40, 30]; assert_eq!(Some(&30), v.last()); let w: &[i32] = &[]; assert_eq!(None, w.last()); }let v = [10, 40, 30]; assert_eq!(Some(&30), v.last()); let w: &[i32] = &[]; assert_eq!(None, w.last());
fn last_mut(&mut self) -> Option<&mut T>
Returns a mutable pointer to the last item in the slice.
fn get(&self, index: usize) -> Option<&T>
Returns the element of a slice at the given index, or None if the
index is out of bounds.
Examples
fn main() { let v = [10, 40, 30]; assert_eq!(Some(&40), v.get(1)); assert_eq!(None, v.get(3)); }let v = [10, 40, 30]; assert_eq!(Some(&40), v.get(1)); assert_eq!(None, v.get(3));
fn get_mut(&mut self, index: usize) -> Option<&mut T>
Returns a mutable reference to the element at the given index,
or None if the index is out of bounds
unsafe fn get_unchecked(&self, index: usize) -> &T
Returns a pointer to the element at the given index, without doing bounds checking.
unsafe fn get_unchecked_mut(&mut self, index: usize) -> &mut T
Returns an unsafe mutable pointer to the element in index
fn as_ptr(&self) -> *const T
Returns an raw pointer to the slice's buffer
The caller must ensure that the slice outlives the pointer this function returns, or else it will end up pointing to garbage.
Modifying the slice may cause its buffer to be reallocated, which would also make any pointers to it invalid.
fn as_mut_ptr(&mut self) -> *mut T
Returns an unsafe mutable pointer to the slice's buffer.
The caller must ensure that the slice outlives the pointer this function returns, or else it will end up pointing to garbage.
Modifying the slice may cause its buffer to be reallocated, which would also make any pointers to it invalid.
fn swap(&mut self, a: usize, b: usize)
Swaps two elements in a slice.
Arguments
- a - The index of the first element
- b - The index of the second element
Panics
Panics if a or b are out of bounds.
Example
fn main() { let mut v = ["a", "b", "c", "d"]; v.swap(1, 3); assert!(v == ["a", "d", "c", "b"]); }let mut v = ["a", "b", "c", "d"]; v.swap(1, 3); assert!(v == ["a", "d", "c", "b"]);
fn reverse(&mut self)
Reverse the order of elements in a slice, in place.
Example
fn main() { let mut v = [1, 2, 3]; v.reverse(); assert!(v == [3, 2, 1]); }let mut v = [1, 2, 3]; v.reverse(); assert!(v == [3, 2, 1]);
fn iter(&self) -> Iter<T>
Returns an iterator over the slice.
fn iter_mut(&mut self) -> IterMut<T>
Returns an iterator that allows modifying each value
fn windows(&self, size: usize) -> Windows<T>
Returns an iterator over all contiguous windows of length
size. The windows overlap. If the slice is shorter than
size, the iterator returns no values.
Panics
Panics if size is 0.
Example
Print the adjacent pairs of a slice (i.e. [1,2], [2,3],
[3,4]):
let v = &[1, 2, 3, 4]; for win in v.windows(2) { println!("{:?}", win); }
fn chunks(&self, size: usize) -> Chunks<T>
Returns an iterator over size elements of the slice at a
time. The chunks do not overlap. If size does not divide the
length of the slice, then the last chunk will not have length
size.
Panics
Panics if size is 0.
Example
Print the slice two elements at a time (i.e. [1,2],
[3,4], [5]):
let v = &[1, 2, 3, 4, 5]; for win in v.chunks(2) { println!("{:?}", win); }
fn chunks_mut(&mut self, chunk_size: usize) -> ChunksMut<T>
Returns an iterator over chunk_size elements of the slice at a time.
The chunks are mutable and do not overlap. If chunk_size does
not divide the length of the slice, then the last chunk will not
have length chunk_size.
Panics
Panics if chunk_size is 0.
fn split_at(&self, mid: usize) -> (&[T], &[T])
Divides one slice into two at an index.
The first will contain all indices from [0, mid) (excluding
the index mid itself) and the second will contain all
indices from [mid, len) (excluding the index len itself).
Panics
Panics if mid > len.
Examples
fn main() { let v = [10, 40, 30, 20, 50]; let (v1, v2) = v.split_at(2); assert_eq!([10, 40], v1); assert_eq!([30, 20, 50], v2); }let v = [10, 40, 30, 20, 50]; let (v1, v2) = v.split_at(2); assert_eq!([10, 40], v1); assert_eq!([30, 20, 50], v2);
fn split_at_mut(&mut self, mid: usize) -> (&mut [T], &mut [T])
Divides one &mut into two at an index.
The first will contain all indices from [0, mid) (excluding
the index mid itself) and the second will contain all
indices from [mid, len) (excluding the index len itself).
Panics
Panics if mid > len.
Example
fn main() { let mut v = [1, 2, 3, 4, 5, 6]; // scoped to restrict the lifetime of the borrows { let (left, right) = v.split_at_mut(0); assert!(left == []); assert!(right == [1, 2, 3, 4, 5, 6]); } { let (left, right) = v.split_at_mut(2); assert!(left == [1, 2]); assert!(right == [3, 4, 5, 6]); } { let (left, right) = v.split_at_mut(6); assert!(left == [1, 2, 3, 4, 5, 6]); assert!(right == []); } }let mut v = [1, 2, 3, 4, 5, 6]; // scoped to restrict the lifetime of the borrows { let (left, right) = v.split_at_mut(0); assert!(left == []); assert!(right == [1, 2, 3, 4, 5, 6]); } { let (left, right) = v.split_at_mut(2); assert!(left == [1, 2]); assert!(right == [3, 4, 5, 6]); } { let (left, right) = v.split_at_mut(6); assert!(left == [1, 2, 3, 4, 5, 6]); assert!(right == []); }
fn split<F>(&self, pred: F) -> Split<T, F> where F: FnMut(&T) -> bool
Returns an iterator over subslices separated by elements that match
pred. The matched element is not contained in the subslices.
Examples
Print the slice split by numbers divisible by 3 (i.e. [10, 40],
[20], [50]):
let v = [10, 40, 30, 20, 60, 50]; for group in v.split(|num| *num % 3 == 0) { println!("{:?}", group); }
fn split_mut<F>(&mut self, pred: F) -> SplitMut<T, F> where F: FnMut(&T) -> bool
Returns an iterator over mutable subslices separated by elements that
match pred. The matched element is not contained in the subslices.
fn splitn<F>(&self, n: usize, pred: F) -> SplitN<T, F> where F: FnMut(&T) -> bool
Returns an iterator over subslices separated by elements that match
pred, limited to returning at most n items. The matched element is
not contained in the subslices.
The last element returned, if any, will contain the remainder of the slice.
Examples

[20, 60, 50]):
let v = [10, 40, 30, 20, 60, 50]; for group in v.splitn(2, |num| *num % 3 == 0) { println!("{:?}", group); }
fn splitn_mut<F>(&mut self, n: usize, pred: F) -> SplitNMut<T, F> where F: FnMut(&T) -> bool
Returns an iterator over subslices separated by elements that match
pred, limited to returning at most n items. The matched element is
not contained in the subslices.
The last element returned, if any, will contain the remainder of the slice.
fn rsplitn<F>(&self, n: usize, pred: F) -> RSplitN<T, F> where F: FnMut(&T) -> bool
Returns an iterator over subslices separated by elements that match
pred limited to returning at most n items. This starts at the end of
the slice and works backwards. The matched element is not contained in
the subslices.
The last element returned, if any, will contain the remainder of the slice.
Examples
Print the slice split once, starting from the end, by numbers divisible
by 3 (i.e. [50], [10, 40, 30, 20]):
let v = [10, 40, 30, 20, 60, 50]; for group in v.rsplitn(2, |num| *num % 3 == 0) { println!("{:?}", group); }
fn rsplitn_mut<F>(&mut self, n: usize, pred: F) -> RSplitNMut<T, F> where F: FnMut(&T) -> bool
Returns an iterator over subslices separated by elements that match
pred limited to returning at most n items. This starts at the end of
the slice and works backwards. The matched element is not contained in
the subslices.
The last element returned, if any, will contain the remainder of the slice.
fn contains(&self, x: &T) -> bool where T: PartialEq<T>
Returns true if the slice contains an element with the given value.
Examples
fn main() { let v = [10, 40, 30]; assert!(v.contains(&30)); assert!(!v.contains(&50)); }let v = [10, 40, 30]; assert!(v.contains(&30)); assert!(!v.contains(&50));
fn starts_with(&self, needle: &[T]) -> bool where T: PartialEq<T>
Returns true if needle is a prefix of the slice.
Examples
fn main() { let v = [10, 40, 30]; assert!(v.starts_with(&[10])); assert!(v.starts_with(&[10, 40])); assert!(!v.starts_with(&[50])); assert!(!v.starts_with(&[10, 50])); }let v = [10, 40, 30]; assert!(v.starts_with(&[10])); assert!(v.starts_with(&[10, 40])); assert!(!v.starts_with(&[50])); assert!(!v.starts_with(&[10, 50]));
fn ends_with(&self, needle: &[T]) -> bool where T: PartialEq<T>
Returns true if needle is a suffix of the slice.
Examples
fn main() { let v = [10, 40, 30]; assert!(v.ends_with(&[30])); assert!(v.ends_with(&[40, 30])); assert!(!v.ends_with(&[50])); assert!(!v.ends_with(&[50, 30])); }let v = [10, 40, 30]; assert!(v.ends_with(&[30])); assert!(v.ends_with(&[40, 30])); assert!(!v.ends_with(&[50])); assert!(!v.ends_with(&[50, 30]));
fn binary_search(&self, x: &T) -> Result<usize, usize> where T: Ord
Binary search a sorted slice for a given element.
If the value is found then Ok is returned, containing the
index of the matching element; if the value is not found then
Err is returned, containing the index where a matching
element could be inserted while maintaining sorted order.
Example
Looks up a series of four elements. The first is found, with a
uniquely determined position; the second and third are not
found; the fourth could match any position in [1,4].
let s = [0, 1, 1, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55]; assert_eq!(s.binary_search(&13), Ok(9)); assert_eq!(s.binary_search(&4), Err(7)); assert_eq!(s.binary_search(&100), Err(13)); let r = s.binary_search(&1); assert!(match r { Ok(1...4) => true, _ => false, });
fn binary_search_by<F>(&self, f: F) -> Result<usize, usize> where F: FnMut(&T) -> Ordering
Binary search a sorted slice with a comparator function.
The comparator function should implement an order consistent
with the sort order of the underlying slice, returning an
order code that indicates whether its argument is Less,
Equal or Greater the desired target.
If a matching value is found then returns Ok, containing
the index for the matched element; if no match is found then
Err is returned, containing the index where a matching
element could be inserted while maintaining sorted order.
Example
Looks up a series of four elements. The first is found, with a
uniquely determined position; the second and third are not
found; the fourth could match any position in [1,4].
let s = [0, 1, 1, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55]; let seek = 13; assert_eq!(s.binary_search_by(|probe| probe.cmp(&seek)), Ok(9)); let seek = 4; assert_eq!(s.binary_search_by(|probe| probe.cmp(&seek)), Err(7)); let seek = 100; assert_eq!(s.binary_search_by(|probe| probe.cmp(&seek)), Err(13)); let seek = 1; let r = s.binary_search_by(|probe| probe.cmp(&seek)); assert!(match r { Ok(1...4) => true, _ => false, });
fn sort(&mut self) where T: Ord
Sorts the slice, in place.
This is equivalent to self.sort_by(|a, b| a.cmp(b)).
This is a stable sort.
Examples
fn main() { let mut v = [-5, 4, 1, -3, 2]; v.sort(); assert!(v == [-5, -3, 1, 2, 4]); }let mut v = [-5, 4, 1, -3, 2]; v.sort(); assert!(v == [-5, -3, 1, 2, 4]);
fn sort_by_key<B, F>(&mut self, f: F) where B: Ord, F: FnMut(&T) -> B
Sorts the slice, in place, using key to extract a key by which to
order the sort by.
This sort is O(n log n) worst-case and stable, but allocates
approximately 2 * n, where n is the length of self.
This is a stable sort.
Examples
#![feature(slice_sort_by_key)] fn main() { let mut v = [-5i32, 4, 1, -3, 2]; v.sort_by_key(|k| k.abs()); assert!(v == [1, 2, -3, 4, -5]); }#![feature(slice_sort_by_key)] let mut v = [-5i32, 4, 1, -3, 2]; v.sort_by_key(|k| k.abs()); assert!(v == [1, 2, -3, 4, -5]);
fn sort_by<F>(&mut self, compare: F) where F: FnMut(&T, &T) -> Ordering
Sorts the slice, in place, using compare to compare
elements.
This sort is O(n log n) worst-case and stable, but allocates
approximately 2 * n, where n is the length of self.
Examples
fn main() { let mut v = [5, 4, 1, 3, 2]; v.sort_by(|a, b| a.cmp(b)); assert!(v == [1, 2, 3, 4, 5]); // reverse sorting v.sort_by(|a, b| b.cmp(a)); assert!(v == [5, 4, 3, 2, 1]); }let mut v = [5, 4, 1, 3, 2]; v.sort_by(|a, b| a.cmp(b)); assert!(v == [1, 2, 3, 4, 5]); // reverse sorting v.sort_by(|a, b| b.cmp(a)); assert!(v == [5, 4, 3, 2, 1]);
fn clone_from_slice(&mut self, src: &[T]) -> usize where T: Clone
clone_from_slice #27750)Copies as many elements from src as it can into self (the
shorter of self.len() and src.len()). Returns the number
of elements copied.
Example
#![feature(clone_from_slice)] fn main() { let mut dst = [0, 0, 0]; let src = [1, 2]; assert!(dst.clone_from_slice(&src) == 2); assert!(dst == [1, 2, 0]); let src2 = [3, 4, 5, 6]; assert!(dst.clone_from_slice(&src2) == 3); assert!(dst == [3, 4, 5]); }#![feature(clone_from_slice)] let mut dst = [0, 0, 0]; let src = [1, 2]; assert!(dst.clone_from_slice(&src) == 2); assert!(dst == [1, 2, 0]); let src2 = [3, 4, 5, 6]; assert!(dst.clone_from_slice(&src2) == 3); assert!(dst == [3, 4, 5]);
fn to_vec(&self) -> Vec<T> where T: Clone
Copies self into a new Vec.
fn into_vec(self: Box<[T]>) -> Vec<T>
Converts self into a vector without clones or allocation.
