Extensible, strongly-typed OAuth2 implementation supporting RFC 6749 flows, token handling, and pluggable configuration; faithful line-by-line transliteration aiming for full feature parity with upstream.
This is a Kotlin Multiplatform line-by-line transliteration port of ramosbugs/oauth2-rs.
Original Project: This port is based on ramosbugs/oauth2-rs. All design credit and project intent belong to the upstream authors; this repository is a faithful port to Kotlin Multiplatform with no behavioural changes intended.
This is an in-progress port. The goal is feature parity with the upstream Rust crate while providing a native Kotlin Multiplatform API. Every Kotlin file carries a // port-lint: source <path> header naming its upstream Rust counterpart so the AST-distance tool can track provenance.
ramosbugs/oauth2-rsThe text below is reproduced and lightly edited from
https://github.com/ramosbugs/oauth2-rs. It is the upstream project's own description and remains under the upstream authors' authorship; links have been rewritten to absolute upstream URLs so they continue to resolve from this repository.
An extensible, strongly-typed implementation of OAuth2 (RFC 6749).
Documentation is available on docs.rs. Release notes are available on GitHub.
For authentication (e.g., single sign-on or social login) purposes, consider using the
openidconnect crate, which is built on top of
this one.
The MSRV for 5.1 and newer releases of this crate is Rust 1.71.
The MSRV for 5.0.y releases of this crate is Rust 1.65.
The MSRV for 4.x releases of this crate is Rust 1.45.
Beginning with the 5.0.0 release, 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. MSRV changes will coincide with minor version updates and will not happen in patch releases.
