2019-07-24Rollup merge of #62772 - estebank:trait-bound, r=matthewjasperMazdak Farrokhzad-3/+5
Suggest trait bound on type parameter when it is unconstrained Given ``` trait Foo { fn method(&self) {} } fn call_method<T>(x: &T) { x.method() } ``` suggest constraining `T` with `Foo`. Fix #21673, fix #41030.
2019-07-19Auto merge of #62684 - petrochenkov:scopevisit, r=davidtwcobors-23/+6
resolve: Improve candidate search for unresolved macro suggestions Use same scope visiting machinery for both collecting suggestion candidates and actually resolving the names. The PR is better read in per-commit fashion with whitespace changes ignored (the first commit in particular moves some code around). This should be the last pre-requisite for https://github.com/rust-lang/rust/pull/62086. r? @davidtwco

2019-07-18resolve: Use `feature(custom_attribute)` fallback only if the feature is enabledVadim Petrochenkov-23/+6
Normally `#![feature(...)]` shouldn't change behavior, but custom attributes in particular are in the process of retirement, and we should not produce a message telling to enable them. It also helps with unifying diagnostics for unresolved macros.

2019-05-31Add more detail to type inference errorEsteban Küber-2/+2
When encountering code where type inference fails, add more actionable information: ``` fn main() { let foo = Vec::new(); } ``` ``` error[E0282]: type annotations needed for `std::vec::Vec<_>` --> $DIR/vector-no-ann.rs:2:16 | LL | let foo = Vec::new(); | --- ^^^^^^^^ cannot infer type for `T` | | | consider giving `foo` the type `std::vec::Vec<_>` with the type parameter `T` specified ``` We still need to modify type printing to optionally accept a `TypeVariableTable` in order to properly print `std::vec::Vec<T>`. CC #25633.
