This code is a thrown-together demo of dropping "late" UDP packets: packets that arrived while previous packet processing was in-flight and are now stale. Processing time is simulated with a sleep (as usual).
This demo was inspired by a Reddit question.
Open two terminals. On the first, say cargo run --bin receive. On the second say cargo run --bin send.
The consumer will block waiting for the first message to be
sent. The first message printed once send starts will most
likely be greater than 0, as the receive thread is racing
with the consumer. The interval between "processed" packets
in the receive window should be quite large. When the
sender is interrupted, the consumer should immediately
block. Restart the sender to send more messages.
