rusty-lox

This is an implementation of lox in rust through chapter 11 of the book.

It contains:

• User declared functions, with recursion
• Built in timing function
• Basic addition and order of operation

with a recursive descent parser from the book ported from Java to Rust.

$ cat fib.lox 
fun fib(n) {
    if (n <= 1) return n;
    return fib(n - 2) + fib(n - 1);
}
var start = clock();
print "fib(30):";
print fib(30);
var end = clock();
print "Time:";
print end - start;

$ cargo run --release fib.lox

This was a solo hackathon project for the year.
