[−][src]Struct tower::balance::pool::Pool

pub struct Pool<MS, Target, Request> where
    MS: MakeService<Target, Request>,
    MS::MakeError: Into<BoxError>,
    MS::Error: Into<BoxError>,
    Target: Clone,  { /* fields omitted */ }

This is supported on crate feature balance only.

A dynamically sized, load-balanced pool of Service instances.

Implementations

`impl<MS, Target, Request> Pool<MS, Target, Request> where MS: MakeService<Target, Request>, MS::Service: Load, <MS::Service as Load>::Metric: Debug, MS::MakeError: Into<BoxError>, MS::Error: Into<BoxError>, Target: Clone,` [src]

`pub fn new(make_service: MS, target: Target) -> Self`[src]

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.
