Trait tower_make::MakeConnection[−][src]

pub trait MakeConnection<Target>: Sealed<(Target,)> {
    type Connection: AsyncRead + AsyncWrite;
    type Error;
    type Future: Future<Output = Result<Self::Connection, Self::Error>>;
    fn poll_ready(
        &mut self, 
        cx: &mut Context<'_>
    ) -> Poll<Result<(), 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.
