# rustup-version-name

Show the used Rust toolchain version name for the current working directory.

If you use [rustup](https://github.com/rust-lang-nursery/rustup.rs)
you may have toolchain overrides for certain directories.
Sometimes it is good to see which one that is.
Put it in your prompt and it is there when you need to know.
