Struct tower_balance::pool::Pool [−][src]
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]
MS: MakeService<Target, Request>,

<MS::Service as Load>::Metric: Debug,
MS::MakeError: Into<Box<dyn Error + Send + Sync>>,
MS::Error: Into<Box<dyn Error + Send + Sync>>,
Target: Clone,
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.
