Function file_system::set_permissions

pub fn set_permissions<P>(path: P, perm: Permissions) -> Result<(), Error> where
    P: AsRef<Path>, 

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.

Errors

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.

Examples

use std::fs;

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