Minimum Supported Rust Version (MSRV)

The MSRV for 2.x releases of this crate is Rust 1.45. The upcoming release of 3.0.0 is expected to target Rust 1.57 or later. Beginning with 3.0.0, this crate will maintain a policy of supporting Rust releases going back at least 6 months. Changes that break compatibility with Rust releases older than 6 months will no longer be considered SemVer breaking changes and will not result in a new major version number for this crate.
