pub struct TokenBucketLimiter { /* private fields */ }
Expand description

Token bucket rate limiter

Implements the token bucket algorithm for rate limiting API calls. Tokens are added at a fixed rate, and each request consumes tokens. If insufficient tokens are available, the request is rate limited.

Implementations§

Source§

impl TokenBucketLimiter

Source

pub fn new(tokens_per_second: f64, max_tokens: f64) -> Self

Create a new token bucket limiter

§Arguments
  • tokens_per_second - Rate at which tokens are added (e.g., 10 for 10 requests/sec)
  • max_tokens - Maximum tokens in bucket (burst capacity)
Source

pub fn try_acquire(&mut self, tokens: f64) -> bool

Try to acquire tokens

Returns true if tokens were acquired, false if rate limited

Source

pub async fn acquire(&mut self, tokens: f64)

Wait until tokens are available

Blocks until the specified number of tokens are available

Source

pub fn current_tokens(&mut self) -> f64

Get current token count

Source

pub fn time_until_available(&mut self, tokens: f64) -> Duration

Get time until tokens are available
