# rust-quale
A Rust port of the `which` utility. Locates an executable in the user’s path.
‘Quale’ is an Italian translation of the English word ‘which’.
*Note: rust-quale currently only works on Unix-like operating systems.*
## Usage
```toml
[dependencies]
quale = "1.0"
```
```rust
extern crate quale;
use quale::which;
fn main() {
assert_eq!(
which("sh"),
Some("/bin/sh".into()));
assert_eq!(
which("foobar"),
None);
}
```
