Avoid describing a method as 'not found' when bounds are unsatisfied Fixes #76267 When there is a single applicable method candidate, but its trait bounds are not satisfied, we avoid saying that the method is "not found". Insted, we update the error message to directly mention which bounds are not satisfied, rather than mentioning them in a note. 2020-09-26 17:20:14 -04:00			`let _j = i.clone(); //~ ERROR the method`
core: split into fmt::Show and fmt::String fmt::Show is for debugging, and can and should be implemented for all public types. This trait is used with `{:?}` syntax. There still exists #[derive(Show)]. fmt::String is for types that faithfully be represented as a String. Because of this, there is no way to derive fmt::String, all implementations must be purposeful. It is used by the default format syntax, `{}`. This will break most instances of `{}`, since that now requires the type to impl fmt::String. In most cases, replacing `{}` with `{:?}` is the correct fix. Types that were being printed specifically for users should receive a fmt::String implementation to fix this. Part of #20013 [breaking-change] 2014-12-20 00:09:35 -08:00			`println!("{:?}", i);`
