Struct LimitedSemaphore 

pub struct LimitedSemaphore { /* private fields */ }

A semaphore paired with its configured permit limit, so utilization can be computed.

The two are bound together because a semaphore’s available_permits() is meaningless for utilization without knowing the limit it was created with. Construct this where the semaphore is created so the pair can never drift.

Implementations

impl LimitedSemaphore

pub fn new(limit: usize) -> LimitedSemaphore

Creates a semaphore with limit permits, paired with that limit. Constructing the semaphore here (rather than accepting a pre-built one) guarantees the stored limit always matches the semaphore’s actual capacity.

pub fn limit(&self) -> usize

The configured permit limit this semaphore was created with.
