Function std::fs::rename [] [src]

pub fn rename<P: AsRef<Path>, Q: AsRef<Path>>(from: P, to: Q) -> Result<()>

Rename a file or directory to a new name.

This will not work if the new name is on a different mount point.


This function will return an error if the provided from doesn't exist, if the process lacks permissions to view the contents, if from and to reside on separate filesystems, or if some other intermittent I/O error occurs.


fn main() { use std::fs; fn foo() -> std::io::Result<()> { try!(fs::rename("a.txt", "b.txt")); Ok(()) } }
use std::fs;

try!(fs::rename("a.txt", "b.txt"));
