Struct KeyedLimiter 

Source 
pub struct KeyedLimiter<K: Eq + Hash + Clone> { /* private fields */ }
Expand description

Limit the concurrency of some keyed operation without blocking.

Implementations§

Source§

impl<K: Eq + Hash + Clone> KeyedLimiter<K>

Source

pub fn new(max: NonZeroU32) -> Self

Create a limiter that allows up to max concurrent reservations.

Source

pub fn try_acquire(&self, key: K) -> Option<KeyedReservation<K>>

Attempt to reserve a slot for a given key. Returns None when the limiter is saturated or the key is already reserved.
