Expand description

RuntimeProvider defines which async runtime that handles IO and timers.

Required Associated Types§

source

type Handle: Clone + Send + Spawn + Sync + Unpin

Handle to the executor;

source

type Timer: Time + Send + Unpin

Timer

source

Required Methods§

source

fn create_handle(&self) -> Self::Handle

Create a runtime handle

source

fn connect_tcp( &self, server_addr: SocketAddr, ) -> Pin<Box<dyn Send + Future<Output = Result<Self::Tcp>>>>

Create a TCP connection with custom configuration.

source

fn bind_udp( &self, local_addr: SocketAddr, server_addr: SocketAddr, ) -> Pin<Box<dyn Send + Future<Output = Result<Self::Udp>>>>

Create a UDP socket bound to local_addr. The returned value should not be connected to server_addr. Notice: the future should be ready once returned at best effort. Otherwise UDP DNS may need much more retries.
