io_multiplexer.h File Reference

Detailed Description

Multiplexers for selecting one of several I/O interfaces.

We define a "port" as a Readable pointer paired with a Writeable pointer, representing input from and output to the same logical interface. Examples include a UART (cfg::Uart), or a MailMap object (port::Mailbox), or a UDP socket (udp::Socket).

A "controller" is anything that attaches to a port and begins issuing read and write commands, such as an Ethernet network interface (eth::Dispatch) or a port adapter (port::MailAdapter, port::SlipAdapter). Some objects act as both a port and a controller, such as BufferedIO (io::BufferedIO).
