Struct TokenBucket 

Source 
pub struct TokenBucket { /* private fields */ }
Expand description

Token bucket rate limiter.

Provides a rate tokens-per-second refill up to capacity, and allows consuming one token at a time via allow. Mirrors golang.org/x/time/rate.Limiter.

Implementations§

Source§

impl TokenBucket

Source

pub fn new(rate: f64, burst: usize) -> Self

Creates a new TokenBucket with the given rate (tokens per second) and burst capacity.

The bucket starts full.

Source

pub fn allow(&mut self) -> bool

Attempt to consume one token. Returns true if a token was available.
