Struct OAuth2Provider 

pub struct OAuth2Provider { /* private fields */ }

Provider for OAuth 2.0 client-credentials authentication.

On each request, ensures a valid cached access token (fetching one from the token endpoint via the client_credentials grant when missing or expired) and injects it as an Authorization: Bearer <token> header.

The client secret and cached tokens are zeroized on drop to prevent lingering sensitive data in memory.

Implementations

impl OAuth2Provider

pub fn new( token_endpoint: String, client_id: String, client_secret: String, scope: Option<String>, ) -> Self

Create a new OAuth 2.0 client-credentials auth provider.

token_endpoint is the full URL of the OAuth 2.0 token endpoint. scope is optional and sent as the scope form parameter when present.

where Self: 'async_trait, 'life0: 'async_trait,
