Struct LockFreeRateLimiter

#[repr(align(64))]
pub struct LockFreeRateLimiter { /* private fields */ }

Ultra-low-latency rate limiter designed for HFT applications Uses lock-free algorithms to eliminate async/await overhead in critical paths

Implementations

impl LockFreeRateLimiter

pub fn new(max_tokens: NonZeroUsize, window: Duration) -> Self

Create a new lock-free rate limiter

pub fn try_acquire(&self) -> TokenGuard<'_>

Try to acquire a token without waiting (lock-free fast path)

pub fn acquire(&self) -> TokenGuard<'_>

Wait until a token becomes available (may block briefly), returns RAII guard

pub const fn max_tokens(&self) -> usize

Get the maximum tokens

pub fn available_tokens(&self) -> usize

Get the current available tokens

pub const fn window(&self) -> Duration

Get the window duration
