## Alternatives
This crate is dead simple with no dependencies. If you need something more
and don't care about panicking if the version cannot be obtained, or if you
don't mind adding dependencies, see
[rustc_version](https://crates.io/crates/rustc_version).
This crate is dead simple with no dependencies. If you need something more and
don't care about panicking if the version cannot be obtained, or if you don't
mind adding dependencies, see [rustc_version]. If you'd instead prefer a feature
detection library that works by dynamically invoking `rustc` with a
representative code sample, see [autocfg].
