Add test demonstrating existing behaviour. This commit adds a test that demonstrates the compiler's current behaviour when a function attempts to return a value that was unwrapped by a `?` operator when the omission of `?` would have made the code compile. 2019-04-07 22:19:58 +00:00			`error[E0308]: try expression alternatives have incompatible types`
Suggest removing `?` to resolve type errors. This commit adds a suggestion to remove the `?` from expressions if removing the `?` would resolve a type error. 2019-04-10 21:26:45 +00:00			`--> $DIR/issue-59756.rs:13:5`

Emit coercion suggestions in more places Fixes #66910 We have several different kinds of suggestions we can try to make when type coercion fails. However, we were previously only emitting these suggestions from `demand_coerce_diag`. This resulted in the compiler failing to emit applicable suggestions in several different cases, such as when the implicit return value of a function had the wrong type. This commit adds a new `emit_coerce_suggestions` method, which tries to emit a number of related suggestions. This method is called from both `demand_coerce_diag` and `CoerceMany::coerce_inner`, which covers a much wider range of cases than before. We now suggest using `.await` in more cases where it is applicable, among other improvements. 2019-12-04 01:32:50 +00:00			\| ^^^^^^ expected enum `std::result::Result`, found struct `A`
