Struct ConcurrencyLimit
pub struct ConcurrencyLimit<T> { /* private fields */ }Enforces a limit on the concurrent number of requests the underlying service can handle.
Implementations
impl<T> ConcurrencyLimit<T>
fn new(inner: T, max: usize) -> SelfCreate a new concurrency limiter.
fn with_semaphore(inner: T, semaphore: Arc<Semaphore>) -> SelfCreate a new concurrency limiter with a provided shared semaphore
fn get_ref(&self) -> &TGet a reference to the inner service
fn get_mut(&mut self) -> &mut TGet a mutable reference to the inner service
fn into_inner(self) -> TConsume
self, returning the inner service
