Struct TokenBucket

Source

struct TokenBucket {
    tokens: f64,
    last_refill: Instant,
    max_tokens: f64,
    refill_rate: f64,
}

Expand description

Classic token bucket: refilled continuously based on elapsed time, capped at max_tokens; each request consumes one token.

Implementations§

Source §

impl TokenBucket

Source

fn new(max_tokens: f64, refill_rate: f64) -> Self

Source

fn try_consume(&mut self) -> bool

Refills the bucket for the elapsed time, then attempts to take one token; returns false when the request should be rate-limited.
