Upgrade which to 4.4.0 am: a065455574 am: 26caf7138b am: 67111d64eb am: bcfaaa4c96 am: c72a9258f7 Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/which/+/2441940 Change-Id: I95af58c9bb1369e02e6bd7d08d207c4deec5dac7 Signed-off-by: Automerger Merge Worker <android-build-automerger-merge-worker@system.gserviceaccount.com>
A Rust equivalent of Unix command “which”. Locate installed executable in cross platforms.
To find which rustc executable binary is using.
use which::which; let result = which("rustc").unwrap(); assert_eq!(result, PathBuf::from("/usr/bin/rustc"));
After enabling the regex
feature, find all cargo subcommand executables on the path:
use which::which_re; which_re(Regex::new("^cargo-.*").unwrap()).unwrap() .for_each(|pth| println!("{}", pth.to_string_lossy()));
The documentation is available online.
