# 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.

## 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(())
    }
