I'm starting to learn Clojure and as an exercise I've implemented the following functions (written in Java) in Clojure:
private int[] SwapValues(int val1, int val2, int[] array) {
int[] result = new int[array.length];
for (int i = 0; i < array.length; i++) {
if (array[i] == val1)...
Here's a little command-line utility written in Rust that connects to a Denon AV receiver and sends a command, then receives the response. It's a simple TCP client that takes its command from the first argument.

use std::io::prelude::*;
