Expand description

Fixed-rate limiter backed by a token bucket.

Implementations§

Source§

impl TokenBucketLimiter

Source

pub fn new(requests_per_second: u32) -> Self

Creates a new TokenBucketLimiter with the specified rate (requests per second).

§Panics

Panics if requests_per_second is 0.

Trait Implementations§

impl RateLimiter for TokenBucketLimiter

Source§

fn adjust<'life0, 'life1, 'async_trait>( &'life0 self, _response: &'life1 Response, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

A fixed-rate limiter does not adjust based on responses.

Source§

fn acquire<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Blocks until a request is allowed to proceed.
Source§

fn current_delay<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Duration> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Returns the current delay between requests.
