RecoveryPermitter

Struct RecoveryPermitter 

Source
pub struct RecoveryPermitter { /* private fields */ }
Expand description

Bounded in-flight recovery counter.

Implementations§

Source§

impl RecoveryPermitter

Source

pub fn new(max_concurrent: usize) -> Self

Create a permitter that allows up to max_concurrent parallel recoveries.

Source

pub fn capacity(&self) -> usize

Maximum permits ever issued (i.e. construction-time capacity).

Source

pub fn available(&self) -> usize

Permits currently available — i.e. how many more recoveries could begin right now without blocking.

Source

pub fn in_flight(&self) -> usize

Permits currently held by callers (waiting on or driving a recovery).

Source

pub async fn acquire(&self) -> Option<OwnedSemaphorePermit>

Block until a permit is available.

Returns None if the permitter has been closed, so callers can map the result onto EventsourcedError::PermitDenied cleanly.

Source

pub fn try_acquire(&self) -> Result<OwnedSemaphorePermit, TryAcquireError>

Try to acquire a permit without waiting. Returns Err(_) if no permit is available right now.

Source

pub fn close(&self)

Drain the permitter — pending and future acquires return None so shutdown can short-circuit.
