Required Methods

fn get_token<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Self::Token, GetTokenError>> + Send + 'async_trait>>

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

fn clear_token<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<(), ClearTokenError>> + Send + 'async_trait>>

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

Provided Methods

fn valid<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = bool> + Send + 'async_trait>>

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

Check if the token is valid. The default implementation checks if the token can be acquired via Credentials::get_token.
