Trait NixPath

pub trait NixPath {
    // Required methods
    fn is_empty(&self) -> bool;
    fn len(&self) -> usize;
    fn with_nix_path<T, F>(&self, f: F) -> Result<T>
       where F: FnOnce(&CStr) -> T;
}

Common trait used to represent file system paths by many Nix functions.

Required Methods

fn is_empty(&self) -> bool

Is the path empty?

fn len(&self) -> usize

Length of the path in bytes

fn with_nix_path<T, F>(&self, f: F) -> Result<T>

where F: FnOnce(&CStr) -> T,

Execute a function with this path as a CStr.

Mostly used internally by Nix.

Object Safety

This trait is not object safe.
