Struct RateTracker 

pub struct RateTracker { /* private fields */ }

Circular buffer for tracking requests per minute.

Uses 60-second sliding window for rate burst detection. Memory: ~520 bytes (64 timestamps)

Implementations

impl RateTracker

pub fn new() -> Self

Create a new rate tracker.

pub fn record(&mut self, now_ms: u64) -> f64

Record a request and return current rate (requests per minute).

pub fn current_rate(&self, now_ms: u64) -> f64

Get current rate without recording (requests per minute).

pub fn rate_in_window(&self, now_ms: u64, window_ms: u64) -> f64

Get rate for a custom window (in milliseconds).

pub fn request_count(&self) -> u8

Get the number of requests recorded (up to buffer size).

pub fn last_request_time(&self) -> Option<u64>

Get the most recent timestamp.

pub fn clear(&mut self)

Clear all recorded timestamps.

pub fn is_burst(&self, now_ms: u64, baseline_rate: f64, multiplier: f64) -> bool

Check if there’s a burst (rate exceeds multiplier * baseline).
