I uploaded the code into playground here. Thank Jul 8, 2020 · Given an enum where some variant (s) have named fields (struct variants, anonymous structs), enum S { Unnamed(i32), Named { a: i32 }, } how can we match pairs of them to write a reasonable equality function (without nested matches, and when we can't rely on a #[derive(PartialEq, Eq)])? To learn more about enums and type aliases, you can read the stabilization report from when this feature was stabilized into Rust. Thank you in advance.
