What would be the idiomatic way for the function `eval` to provide good error messages in Rust?
- rtpg 3y agoI would probably put a trait implementatoin on Value that does `.invert_bool`, and have that panic. That way eval is just `eval(m).invert_bool()` and if it panics it panics. What you really probably want is to make this a Result type-returning thing, and then have have `not` be a function of type Value -> Result<Value,ErrType>, and then you can do not(eval(m)) and panic at the top-level.
