## Examples
|
||
|
|
|
||
|
|
1) To find which rustc executable binary is using.
|
||
|
|
|
||
|
|
``` rust
|
||
|
|
use which::which;
|
||
|
|
|
||
|
|
let result = which("rustc").unwrap();
|
||
|
|
assert_eq!(result, PathBuf::from("/usr/bin/rustc"));
|
||
|
|
```
|
||
|
|
|
||
|
|
2. After enabling the `regex` feature, find all cargo subcommand executables on the path:
|
||
|
|
|
||
|
|
``` rust
|
||
|
|
use which::which_re;
|
||
|
|
|
||
|
|
which_re(Regex::new("^cargo-.*").unwrap()).unwrap()
|
||
|
|
.for_each(|pth| println!("{}", pth.to_string_lossy()));
|
||
|
|
```
