Struct SlidingWindowRateLimiter 

pub struct SlidingWindowRateLimiter { /* private fields */ }

Sliding window rate limiter implementation.

Tracks individual request timestamps within a time window for precise rate limiting. More memory-intensive than token bucket but provides exact request counting.

Implementations

impl SlidingWindowRateLimiter

pub fn new(max_requests: usize, window_seconds: u64) -> SlidingWindowRateLimiter

Creates a new sliding window rate limiter.

Arguments

• max_requests - Maximum requests allowed in the time window
• window_seconds - Time window duration in seconds

pub fn is_allowed(&self) -> bool

Checks if a request is allowed under the rate limit.

If allowed, records the request timestamp and returns true. Otherwise returns false.

pub fn current_requests(&self) -> usize

Returns the current number of requests in the window.

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.
