A Rust library to get the path of the currently executing process or the the current dynamic library.

The latter is particularly useful for ‘plug-in‘ type dynamic libraries that need to load resources stored relative to the location of the library in the file system.


Add this to your Cargo.toml:

process_path = "0.1.3"

and this to your crate root:

use process_path;


This program prints its path to stdout:

use process_path::get_executable_path;

fn main() {
    let path = get_executable_path();
    match path {
        None => println!("The process path could not be determined"),
        Some(path) => println!("{:?}", path)
