rust-version-check 0.9.2 Check that the installed rustc meets some version requirements
This tiny crate checks that the running or installed rustc meets some version requirements. The version is queried by calling the Rust compiler with
--version. The path to the compiler is determined first via the
RUSTC environment variable. If it is not set, then
rustc is used. If that fails, no determination is made, and calls return None.
