Upgrade Guide

Upgrading from 4.x to 5.x

The 5.0 release includes breaking changes to address several long-standing API issues, along with a few minor improvements. Consider following the tips below to help ensure a smooth upgrade process.

Upgrade Rust to 1.65 or newer

The minimum supported Rust version (MSRV) is now 1.65. Going forward, 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.

Add typestate generic types to Client

Each auth flow depends on one or more server endpoints. For example, the authorization code flow depends on both an authorization endpoint and a token endpoint, while the client credentials flow only depends on a token endpoint. Previously, it was possible to instantiate a Client without a token endpoint and then attempt to use an auth flow that required a token endpoint, leading to errors at runtime. Also, the authorization endpoint was always required, even for auth flows that do not use it.

In the 5.0 release, all endpoints are optional. Typestates are used to statically track, at compile time, which endpoints' setters (e.g., set_auth_uri()) have been called. Auth flows that depend on an endpoint cannot be used without first calling the corresponding setter, which is enforced by the compiler's type checker. This guarantees that certain errors will not arise at runtime.

In addition to unconditional setters (e.g., set_auth_uri()), each endpoint has a corresponding conditional setter (e.g., set_auth_uri_option()) that sets a conditional typestate (EndpointMaybeSet). When the conditional typestate is set, endpoints can be used via fallible methods that return Err(ConfigurationError::MissingUrl(_)) if an endpoint has not been set. This is useful in dynamic scenarios such as OpenID Connect Discovery, in which it cannot be determined until runtime whether an endpoint is configured.

There are three possible typestates, each implementing the EndpointState trait:

• EndpointNotSet: the corresponding endpoint has not been set and cannot be used.
• EndpointSet: the corresponding endpoint has been set and is ready to be used.
• EndpointMaybeSet: the corresponding endpoint may have been set and can be used via fallible methods that return Result<_, ConfigurationError>.

The following code changes are required to support the new interface:

1. Update calls to Client::new() to use the single-argument constructor (which accepts only a ClientId). Use the set_auth_uri(), set_token_uri(), and set_client_secret() methods to set the authorization endpoint,
