Struct Admission Controller &nbsp; Copy item path

impl AdmissionController

pub fn new(config: AdmissionConfig) -> Arc<Self> ⓘ

Create a new controller with the given configuration.

pub fn try_acquire(self: &Arc<Self>) -> Option<AcquireGuard>

Try to acquire a slot.

Returns None if in_flight >= limit, otherwise returns an AcquireGuard that decrements in_flight on drop.

pub fn on_success(&self)

Additive increase: grow the limit by additive_increase, up to max_limit.

pub fn on_overload(&self)

Multiplicative decrease: shrink the limit by multiplicative_decrease, floored at min_limit.

pub fn stats(&self) -> AdmissionStats

Return a snapshot of current admission statistics.

pub fn current_limit(&self) -> usize

Current adaptive concurrency limit.

pub fn in_flight(&self) -> usize

Number of requests currently in flight.
