Struct RateLimiter 

#[non_exhaustive]
pub struct RateLimiter { /* private fields */ }

Token bucket rate limiter — allows burst up to capacity, refills over time.

Implementations

impl RateLimiter

pub fn new(capacity: u32, refill_rate: f64) -> Self

Create a new rate limiter. capacity = max burst size, refill_rate = tokens per second.

pub fn check(&self, key: &str) -> bool

Try to consume one token for the given key (tool name or container ID). Returns true if allowed, false if rate limited.

pub fn reset(&self, key: &str)

Reset the limiter for a key (e.g., when a container is killed).

pub fn remove(&self, key: &str) -> bool

Remove a single key’s bucket. Returns true if the key existed.

pub fn cleanup_stale(&self, max_age: Duration)

Remove all entries whose last activity is older than max_age.

Should be called periodically (e.g. every 5 minutes) to prevent unbounded growth of the bucket map.
