Rate Limiter Module

This module provides rate limiting functionality to prevent exceeding exchange API limits. It implements token bucket algorithm with configurable capacity and refill rate.

§Features

• Token Bucket Algorithm: Classic rate limiting strategy
• Async-Friendly: Built on tokio for async/await support
• Thread-Safe: Uses Arc<Mutex<>> for concurrent access
• Configurable: Flexible capacity and refill rate settings

§Example

use ccxt_core::rate_limiter::{RateLimiter, RateLimiterConfig};
use std::time::Duration;

// Create a rate limiter: 10 requests per second
let config = RateLimiterConfig::new(10, Duration::from_secs(1));
let limiter = RateLimiter::new(config);

// Wait for permission to make a request
limiter.wait().await;
// Make your API request here
