Source 
pub struct WeightBasedRateLimiter { /* private fields */ }
Expand description

A weight-based rate limiter for more complex exchange rate limiting rules

Implementations§

Source§

impl WeightBasedRateLimiter

Source

pub fn new(max_weight: usize, window_milliseconds: u64) -> Self

Creates a new weight-based rate limiter

§Parameters
  • max_weight - Maximum weight allowed per time window
  • window_milliseconds - Time window in milliseconds
Source

pub async fn acquire(&self, weight: usize) -> Result<()>

Acquires permission to make a request with a specific weight, waiting if necessary

§Parameters
  • weight - The weight of the request
§Returns

Ok(()) when permission is granted, or an error if the wait was interrupted

Source

pub fn try_acquire(&self, weight: usize) -> bool

Tries to acquire permission to make a request without waiting

§Parameters
  • weight - The weight of the request
§Returns

true if permission was granted, false if the rate limit would be exceeded

Source

pub fn mark_request(&self, weight: usize)

Marks a request with a specific weight as completed

Source

pub fn remaining_weight(&self) -> usize

Returns the remaining weight available for immediate use
