Struct RateLimiter 

pub struct RateLimiter { /* private fields */ }

Rate limiter using sliding window algorithm

Implementations

impl RateLimiter

pub fn new(max_requests: u32, per_duration: Duration) -> Self

Create a new rate limiter

Arguments

• max_requests - Maximum number of requests allowed
• per_duration - Time window for the rate limit

Example

use lastfm_client::client::RateLimiter;
use std::time::Duration;

// Allow max 5 requests per second
let limiter = RateLimiter::new(5, Duration::from_secs(1));

pub async fn acquire(&self)

Acquire permission to make a request

This will block until a slot is available according to the rate limit

Panics

Panics if acquiring a semaphore permit fails (should be unreachable under normal operation).

pub fn max_requests(&self) -> u32

Get the maximum requests per duration

pub fn per_duration(&self) -> Duration

Get the time duration for the rate limit

pub fn current_count(&self) -> u32

Get the current request count in the current window
