Struct tower_balance::pool::Pool[−][src]

pub struct Pool<MS, Target, Request> where
    MS: MakeService<Target, Request>,
    MS::MakeError: Into<Box<dyn Error + Send + Sync>>,
    MS::Error: Into<Box<dyn Error + Send + Sync>>,
    Target: Clone,  { /* fields omitted */ }
[−]

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<Box<dyn Error + Send + Sync>>,
    MS::Error: Into<Box<dyn Error + Send + Sync>>,
    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.
