Rust errors

Rust has two primary methods of handling errors.

• panic!() halts/exits the program
• Result types are for handle-able errors

panic

• intended for halting application, not control flow
• have backtraces

panic!("tried to X but couldn't Y")

// convert panic to result
// (not intended for native rust code)
let result = panic::catch_unwind(|| {
    panic!("oh no!");
});
