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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
