Subject: [PATCH] Add MSRV to Cargo.toml
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a `rust_version` entry to `Cargo.toml` in order to codify the MSRV
for `cargo` to pick it up. This leads to a more helpful and more
actionable error message, for example:

> error: package `parking_lot v0.12.1 ([…])` cannot be built because
> it requires rustc 1.59 or newer, while the currently active rustc
> version is 1.58.1
