Trait CounterStore 

pub trait CounterStore: Send + Sync {
    // Required method
    fn incr_fixed_window<'life0, 'life1, 'async_trait>(
        &'life0 self,
        key: &'life1 str,
        limit: u64,
        window: Duration,
    ) -> Pin<Box<dyn Future<Output = Result<WindowResult, CounterError>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait,
             'life1: 'async_trait;
}

A backend that counts requests per key within fixed time windows.

Required Methods

fn incr_fixed_window<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, limit: u64, window: Duration, ) -> Pin<Box<dyn Future<Output = Result<WindowResult, CounterError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Atomically counts one request for key in the current fixed window of length window, allowing up to limit requests per window.
