OpenID Connect Library for Rust

This version is a soft-fork of openidconnect-rs from David Ramos. It relaxes the backward-compatibility constraints with older Rust versions to ensure that the latest crates can always be used for projects that depend on those. As much as possible, this crate will try to remain close and up-to-date with the original one.

This library provides extensible, strongly-typed interfaces for the OpenID Connect protocol.

API documentation and examples are available on docs.rs.

Minimum Supported Rust Version (MSRV)

The MSRV for 3.0.y to 3.1.y releases of this crate is Rust 1.57.

The MSRV for 2.x.y releases of this crate is Rust 1.45.

Since the 3.0.0 release, this crate maintains 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.
