which

A Rust equivalent of Unix command which(1).

Example:

To find which rustc executable binary is using:

use which::which;
use std::path::PathBuf;

let result = which::which("rustc").unwrap();
assert_eq!(result, PathBuf::from("/usr/bin/rustc"));

CanonicalPath	An owned, immutable wrapper around a `PathBuf` containing the canonical path of an executable.
Path	An owned, immutable wrapper around a `PathBuf` containing the path of an executable.

which	Find a exectable binary’s path by name.
which_all	Find all binaries with `binary_name` in the path list `paths`, using `cwd` to resolve relative paths.
which_in	Find `binary_name` in the path list `paths`, using `cwd` to resolve relative paths.
which_in_all	Find all binaries with `binary_name` in the path list `paths`, using `cwd` to resolve relative paths.
