Trait AsPath 

pub trait AsPath {
    type Buffer: AsRef<CStr>;

    // Required method
    fn to_path(self) -> Option<Self::Buffer>;
}

The purpose of this is similar to AsRef<Path> but it’s optimized for things that can be directly used as CStr (which is type passed to the underlying system call).

This trait should be implemented for everything for which AsRef<Path> is implemented

Required Associated Types

type Buffer: AsRef<CStr>

The return value of the to_path that holds data copied from the original path (if copy is needed, otherwise it’s just a reference)

Required Methods

fn to_path(self) -> Option<Self::Buffer>

Returns None when path contains a zero byte

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
