Struct `GlobalConcurrencyLimitLayer`

pub struct GlobalConcurrencyLimitLayer { /* private fields */ }

Enforces a limit on the concurrent number of requests the underlying service can handle.

Unlike ConcurrencyLimitLayer, which enforces a per-service concurrency limit, this layer accepts a owned semaphore (Arc<Semaphore>) which can be shared across multiple services.

Cloning this layer will not create a new semaphore.
