Struct TokenBucket 

pub struct TokenBucket { /* private fields */ }

Token bucket rate limiter

Implements the token bucket algorithm for rate limiting:

• Bucket starts full (capacity tokens)
• Each operation consumes one token
• Tokens refill at a fixed rate
• Operations blocked when bucket is empty

Implementations

impl TokenBucket

pub fn new( capacity: u32, tokens_per_refill: u32, refill_interval: Duration, ) -> TokenBucket

Create a new token bucket

pub fn try_acquire(&self) -> bool

Try to consume a token

Returns true if a token was available and consumed, false otherwise.

pub fn available_tokens(&self) -> u32

Get current available tokens

Trait Implementations

impl Debug for TokenBucket

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

Formats the value using the given formatter.
