Struct Driver 

pub struct Driver<S: Session> { /* private fields */ }

Drives a session with caller-supplied time.

Returned by crate::Client::connect and crate::Server::accept. Call poll when external activity wakes the waiter or when the returned deadline is reached, supplying nondecreasing instants; see crate::time::Driver for the contract. Completion is cached, so subsequent polls return the same error.

It holds no session handle: dropping the last crate::Session requests closure on the next poll. Dropping the driver cancels the session, and crate::Session::closed resolves with Error::Cancel. Its Send-ness follows its transport.

Implementations
