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. It changes this: 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` To this: error[E0277]: cannot multiply `i32` by `f32` --> src/lib.rs:2:7 \| 2 \| x * y \| ^ no implementation for `i32 * f32` \| = help: the trait `Mul<f32>` is not implemented for `i32` 2020-10-17 19:59:51 -07:00			error[E0369]: cannot multiply `bool` by `bool`
