Struct tower::load::pending_requests::PendingRequests[−][src]

pub struct PendingRequests<S, C = CompleteOnResponse> { /* fields omitted */ }

This is supported on crate feature load only.

Measures the load of the underlying service using the number of currently-pending requests.

Implementations

`impl<S, C> PendingRequests<S, C>`[src]

`pub fn new(service: S, completion: C) -> Self`[src]

Wraps an S-typed service so that its load is tracked by the number of pending requests.
