Function std::fs::set_permissions

1.1.0 · source ·
pub fn set_permissions<P: AsRef<Path>>(path: P, perm: Permissions) -> Result<()>
Expand description

Changes the permissions found on a file or a directory.

§Platform-specific behavior

This function currently corresponds to the chmod function on Unix and the SetFileAttributes function on Windows. Note that, this may change in the future.


This function will return an error in the following situations, but is not limited to just these cases:

  • path does not exist.
  • The user lacks the permission to change attributes of the file.


use std::fs;

fn main() -> std::io::Result<()> {
    let mut perms = fs::metadata("foo.txt")?.permissions();
    fs::set_permissions("foo.txt", perms)?;
