A rust library to mark/unmark transmitted/received byte boundaries for messages.
```rust let random_texts = [ "Some random", "strings from this array", "are getiing", "picked and being", "converted to", "to bytes", "and", "then suffixed", "with byte marks.", "These", "marked bytes", "are then getting", "stripped off of", "demarcating", "pattern", ];
let mut randomizer = rand::threadrng(); let numstrings: usize = randomizer.genrange(0..1000); let mut origstrings = vec![]; let mut markedbytes = vec![]; for _ in 0..numstrings { //Pick a random index let index = randomizer.genrange(0..randomtexts.len()); //Pick a random string for the given index let pickedstring = randomtexts[index]; //Get the bytes and demarcate with byte marks let mut bytes = pickedstring.asbytes().tovec(); Marks::markbytes(&mut bytes); //Preserve the old string for later validation origstrings.push(pickedstring); //Keep extending the marked bytes markedbytes.extend(bytes); } //Marked bytes may written to a file/sent across the wire //Get the orginal strings back from marked bytes on receipt let unmarked = Marks::unmark(&markedbytes).unwrap().0; //We must get same bytes back with demarcating bytes removed //Lets reconstruct the strings back and validate for i in 0..unmarked.len() { asserteq!( origstrings[i], String::fromutf8(unmarked[i].tovec()).unwrap() ); }
