bors[bot] 5664a2b0b3 Merge #9814 ... 9814: Generate default impl when converting `#[derive(Debug)]` to manual impl r=yoshuawuyts a=yoshuawuyts This patch makes it so when you convert `#[derive(Debug)]` to a manual impl, a default body is provided that's equivalent to the original output of `#[derive(Debug)]`. This should make it drastically easier to write custom `Debug` impls, especially when all you want to do is quickly omit a single field which is `!Debug`. This is implemented for enums, record structs, tuple structs, empty structs - and it sets us up to implement variations on this in the future for other traits (like `PartialEq` and `Hash`). Thanks! ## Codegen diff This is the difference in codegen for record structs with this patch: ```diff struct Foo { bar: String, } impl fmt::Debug for Foo { fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result { - todo!(); + f.debug_struct("Foo").field("bar", &self.bar).finish() } } ``` Co-authored-by: Irina Shestak <shestak.irina@gmail.com> Co-authored-by: Yoshua Wuyts <yoshuawuyts@gmail.com> Co-authored-by: Yoshua Wuyts <yoshuawuyts+github@gmail.com>		2021-08-08 22:30:37 +00:00
