[−][src]Trait tower::MakeConnection

pub trait MakeConnection<Target>: Sealed<(Target,)> where
    <Self::Future as Future>::Item == Self::Connection,
    <Self::Future as Future>::Error == Self::Error, {
type Connection: AsyncRead + AsyncWrite;
type Error;
type Future: Future;
    fn poll_ready(&mut self) -> Result<Async<()>, Self::Error>;

    fn make_connection(&mut self, target: Target) -> Self::Future;
}

The MakeConnection trait is used to create transports

The goal of this service is to allow composable methods for creating AsyncRead + AsyncWrite transports. This could mean creating a TLS based connection or using some other method to authenticate the connection.

Associated Types

type Connection: AsyncRead + AsyncWrite

The transport provided by this service

type Error

Errors produced by the connecting service

type Future: Future

The future that eventually produces the transport

Required methods

fn poll_ready(&mut self) -> Result<Async<()>, Self::Error>

Returns Ready when it is able to make more connections.
