Struct std::ops::Range [−] [src]

pub struct Range<Idx> {
    pub start: Idx,
    pub end: Idx,
}

A (half-open) range which is bounded at both ends.

Fields

start

The lower bound of the range (inclusive).

end

The upper bound of the range (exclusive).

Methods

impl<A> Range<A> where A: Step

fn step_by(self, by: A) -> StepBy<A, Range<A>>

Unstable (step_by #27741)

: recent addition

Creates an iterator with the same range, but stepping by the given amount at each iteration.

The resulting iterator handles overflow by stopping.

Examples

#![feature(step_by)] fn main() { for i in (0..10).step_by(2) { println!("{}", i); } }
#![feature(step_by)]

for i in (0..10).step_by(2) {
    println!("{}", i);
}

This prints:

0
2
4
6
8
