Struct Transfer 

pub struct Transfer(/* private fields */);

A byte on its way out with another on its way in.

Dropping this leaves the wire as it was. The transfer runs to its end, or goes on waiting, with nobody to collect what arrives.

Implementations

impl Transfer

pub fn poll(&self) -> Option<u8>

The byte that arrived, once the transfer has finished.

pub fn abort(self)

Give up.

A transfer that has already finished is left alone, so what arrived is still there to poll.
