Crate spin_connection_semaphore 

Structs

ConnectionPermit

Holds up to two semaphore permits (global + factor-specific). Both permits are released when this value is dropped. All-None permit fields are valid and represent the no-limits case.

Wraps an optional global and an optional factor-specific semaphore.

LimitedSemaphore

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

Functions

metric_histogram_buckets

Custom histogram bucket boundaries for the utilization metrics this crate emits.
