Trait s2n_tls::callbacks::ConnectionFuture

pub trait ConnectionFuture {
    fn poll(
        self: Pin<&mut Self>,
        connection: &mut Connection,
        ctx: &mut Context<'_>
    ) -> Poll<Result<(), Error>>;
}

The Future associated with the async connection callback.

The calling application can provide an instance of ConnectionFuture when implementing an async callback, eg. ClientHelloCallback, if it wants to run an asynchronous operation (disk read, network call). The application can return an error ([Err(error::Error::application())]), to indicate connection failure.

ConfigResolver should be used if the application wants to set a new Config on the connection.

Required Methods

fn poll(
    self: Pin<&mut Self>,
    connection: &mut Connection,
    ctx: &mut Context<'_>
) -> Poll<Result<(), Error>>
