Improve wording of "cannot multiply" type error For example, if you had this code: fn foo(x: i32, y: f32) -> f32 { x * y } You would get this error: error[E0277]: cannot multiply `f32` to `i32` --> src/lib.rs:2:7 \| 2 \| x * y \| ^ no implementation for `i32 * f32` \| = help: the trait `Mul<f32>` is not implemented for `i32` However, that's not usually how people describe multiplication. People usually describe multiplication like how the division error words it: error[E0277]: cannot divide `i32` by `f32` --> src/lib.rs:2:7 \| 2 \| x / y \| ^ no implementation for `i32 / f32` \| = help: the trait `Div<f32>` is not implemented for `i32` So that's what this change does.

Tweak "the following other types implement trait" When any of the suggested impls is an exact match, only show the exact matches. This is particularly relevant for integer types. fix fmt 2022-12-05 16:24:48 -06:00			`<&i32 as Mul<&i32>>`
