Struct PendingRequests
pub struct PendingRequests<S, C = CompleteOnResponse> { /* private fields */ }Measures the load of the underlying service using the number of currently-pending requests.
Implementations
impl<S, C> PendingRequests<S, C>
fn new(service: S, completion: C) -> SelfWraps an
S-typed service so that its load is tracked by the number of pending requests.
