Crate tk_pool

A connection pool implementation for tokio

Documentation | Github | Crate | Examples

A connection pool implementation for tokio. Main features:

1. Works for any request-reply protocol (actually for any Sink)
2. Provides both queue and pushback if needed
3. Allows pipelining (multiple in-flight request when multiplexing)
4. Auto-reconnects on broken connection
5. Adapts when DNS name change

Multiple load-balancing strategies are in to do list.

Example

let mut pool =
    pool_for(|addr| connect(addr))
    .connect_to(ns.subscribe_many(address, default_port))
    .lazy_uniform_connections(2)
    .with_queue_size(10)
    .spawn_on(&core.handle());
