Function std::fs::set_permissions

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

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][changes]. [changes]: ../io/index.html#platform-specific-behavior

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;

let mut perms = fs::metadata("foo.txt")?.permissions();
perms.set_readonly(true);
fs::set_permissions("foo.txt", perms)?;
