Issuer

Required Associated Types

type Key: Hash + Eq + Send + Sync + 'static

The key is used to identify the rate limit.

Required Methods

fn issue<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, req: &'life1 mut Request, depot: &'life2 Depot ) -> Pin<Box<dyn Future<Output = Option<Self::Key>> + Send + 'async_trait>>where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Issue a new key for the request. If it returns None, the request will not be cached.
