Overview

Default reference implementation of the storage contract that Provider uses to persist OAuth state. Holds the two pieces of data the flow saves and reads on every request:

  • tokens: the hash returned by the token endpoint (access_token, optional refresh_token, expires_in, scope, etc.).
  • client_information: the hash returned by Dynamic Client Registration or supplied as pre-registered credentials (client_id, optional client_secret, optional token_endpoint_auth_method).

This class keeps everything in process memory, so the credentials live only for the lifetime of the Ruby process. Applications that need persistence across restarts should supply a custom object responding to the same four-method contract (tokens, save_tokens(t), client_information, save_client_information(info)) and pass it via Provider.new(storage: ...). The shape mirrors Python SDK's TokenStorage Protocol; TypeScript's OAuthClientProvider rolls the same responsibilities into a single object.
