Rust

Receive a Single Byte from a Socket

Demonstrates Socket.ReceiveByte, which reads exactly one byte and stores its numeric value in the ReceivedInt property. The argument selects signed or unsigned interpretation.

Background. Fixed-size integers and length prefixes are common building blocks for application-defined binary protocols. Byte order is selectable, with big-endian being network byte order.
