Trait RateLimiter 

pub trait RateLimiter: Send + Sync {
    // Required method
    fn is_allowed<'life0, 'life1, 'async_trait>(
        &'life0 self,
        key: &'life1 str,
        limit: u32,
    ) -> Pin<Box<dyn Future<Output = bool> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait,
             'life1: 'async_trait;
}

Per-minute request gate: returns true when key is still within limit requests for the current minute, false when the caller must be rejected.

Required Methods

fn is_allowed<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, limit: u32, ) -> Pin<Box<dyn Future<Output = bool> + Send + 'async_trait>>

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

Returns whether key may proceed under limit requests for the current minute.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
