Panic 'op-assigment operator'

[lroobrou]

After bumping rhai from 1.3.0 to 1.4.0, I received a panic when loading some scripts, with the following message.

thread 'main' panicked at 'op-assignment operator'

The panic occurs at src/ast/stmt.rs:49:14. I turns out that assignments of the form var = var + integer are causing this. Here is an example program that panics with 1.4.0, which runs just fine with 1.3.0.

extern crate rhai;

use std::error::Error;

fn main() -> Result<(), Box<dyn Error>> {
    let engine = rhai::Engine::new();
    let result: i64 = engine.eval(
        r#"
        let a = 0;
        a = a + 1;  // panics
        a
        "#,
    )?;

    println!("result = {}", result);

    Ok(())
}

Yes, good catch. Dunno how this slipped through...

I'll put out a bug-fix version to fix this soon. In the meantime, you can use x += 1 which should work fine!

1.4.1 is published which should contain this bug fix, among others.

Thanks for raising this. Let me know if the new version solves your problem.

Yes, problem solved. :)
