clox written in Rust

rlox

I'm learning Rust by implementing a bytecode vm for the clox language in the book Crafting Interpreters.

WIP: just finished chapter 25 of the book.

$ cat fib.lox
fun fib(n) {
  if (n < 2) return n;
  return fib(n - 2) + fib(n - 1);
}

var start = clock();
print fib(35);
print clock() - start;

$ time cargo run --release --quiet fib.lox
