}Expand description
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.
Required Associated Types§
sourcetype Connection: AsyncRead + AsyncWrite
type Connection: AsyncRead + AsyncWrite
The transport provided by this service
Required Methods§
sourcefn poll_ready(&mut self, cx: &mut Context<'_>) -> Poll<Result<(), Self::Error>>
fn poll_ready(&mut self, cx: &mut Context<'_>) -> Poll<Result<(), Self::Error>>
Returns Poll::Ready(Ok(())) when it is able to make more connections.
sourcefn make_connection(&mut self, target: Target) -> Self::Future
fn make_connection(&mut self, target: Target) -> Self::Future
Connect and return a transport asynchronously
