Struct Admission 

pub struct Admission { /* private fields */ }

Shared admission gate handed to every per-connection task via lifecycle::AcceptContext. Cheap to clone (just an Arc bump).

Implementations

impl Admission

pub fn new(active_permits: usize, queue_depth: usize) -> Self

Build an admission gate sized for active_permits + queue_depth simultaneous outstanding requests across the daemon.

pub fn try_admit(&self) -> Result<OwnedSemaphorePermit, SubmitError>

Attempt to admit one request. Non-blocking. The returned OwnedSemaphorePermit must be held for the duration of the generation; dropping it returns the slot to the pool.

pub fn capacity(&self) -> usize

Total slots configured (active_permits + queue_depth). Diagnostic only; the wire layer doesn’t surface this.

pub fn available_permits(&self) -> usize

Approximate count of slots currently free. Diagnostic; racy by definition (a concurrent admit can change the answer between the call and the use).

Trait Implementations

impl Clone for Admission

fn clone(&self) -> Admission

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
