The first component is a question of how we can generalize and extend Rust enums to cover more scenarios. And of course I have to make sure not to read those fields without checking what kind of error I have first. I am going to start the series by focusing on the question of extending enums. Heck, you could just write a carefully constructed wrapper around a C union to get what you want.

In Rust, we have the notion of DST to address this problem. So I need dynamic allocation. One more structured solution is to go to a full-blown class hierarchy: In Rust, the size of an ErrorCode instance is equal to the maximum of its variants, which means that we can pass errors around by value and know that we have enough space to store any kind of error.

Mar 27, - You can use pattern matching: struct Point { x: f64, y: f64, } enum Shape { Circle(Point, f64), Rectangle(Point, Point), } fn main() { let my_shape.
