Using reflection to enumerate through the fields of a struct at runtime

Question

If I have a data structure like this:

struct Point {
    x: i32,
    y: i32,
}

impl Point {
    fn setX(&mut self, x: i32) -> &mut Point {
        s         


        

Answer 1

Rust does not really support this kind of reflection at runtime, no.

In theory, you might be able to write a syntax extension that would let you generate some code that would do something like this, maybe...
