Expand description

The common interface for ports, whether for input or output.

Required Methods§

Source

fn close(&mut self)

Closes this port without dropping it, returning immediately.

If the port had an open connection, it will be disconnected. If the port was already closed, no further action is taken. There is no facility to reopen a port once it has been closed.
