Enum State 

enum State<T> {
    Idle(Option<Buf>),
    Busy(JoinHandle<(Result<usize>, Buf, T)>),
}

Variants

Idle(Option<Buf>)

Holds None if an operation could not be spawned, normally because the runtime is shutting down. inner is gone in that case, so all further operations fail.

Busy(JoinHandle<(Result<usize>, Buf, T)>)
