Crate whereismybin
source ·Expand description
Locates installed executable inside directories specified in the PATH environment variable.
The goals of this implementations are:
- No dependencies except the standard library.
- No unsafe code, no syscalls, no calls to libc.
- Compatibility with Miri.
Example
whereismybin can be used as a library. Example:
use std::process::Command;
use whereismybin::whereismybin;
let my_tool = whereismybin("my-tool").expect("Could not find my-tool");
let output = Command::new(my_tool)
.arg("--some-arg")
.output()
.expect("Failed to execute process");
let content = output.stdout;
Why not which-rs?
The which-rs crate is great, but unfortunately it doesn’t run on Miri and depends on libc crate. whereismybin aims to provide more lightweight alternative.
