Struct tower::balance::pool::Pool [−][src]
pub struct Pool<MS, Target, Request> where
MS: MakeService<Target, Request>,
MS::MakeError: Into<BoxError>,
MS::Error: Into<BoxError>,
Target: Clone, { /* fields omitted */ }Expand description
A dynamically sized, load-balanced pool of Service instances.
Implementations
Construct a new dynamically sized Pool.
If many calls to poll_ready return Pending, new_service is used to
construct another Service that is then added to the load-balanced pool.
If many calls to poll_ready succeed, the most recently added Service
is dropped from the pool.
Trait Implementations
Responses given by the service.
Errors produced by the service.
The future response value.
Returns Poll::Ready(Ok(())) when the service is able to process requests. Read more
