Trait CacheIssuer 

pub trait CacheIssuer:
    Send
    + Sync
    + 'static {
    type Key: Hash + Eq + Send + Sync + 'static;

    // Required method
    fn issue(
        &self,
        req: &mut Request,
        depot: &Depot,
    ) -> impl Future<Output = Option<Self::Key>> + Send;
}

Required Associated Types

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

The key is used to identify the rate limit.

Required Methods

fn issue( &self, req: &mut Request, depot: &Depot, ) -> impl Future<Output = Option<Self::Key>> + Send

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

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
