* Fix hover on the beginning of a nested expressionFlorian Diebold2019-04-281-3/+18
| | | | | | | | | | | | | | | | E.g. in ``` let foo = 1u32; if true { <|>foo; } ``` the hover shows `()`, the type of the whole if expression, instead of the more sensible `u32`. The reason for this was that the search for an expression was slightly left-biased: When on the edge between two tokens, it first looked at all ancestors of the left token and then of the right token. Instead merge the ancestors in ascending order, so that we get the smaller of the two possible expressions.

For now, the only supported lang items are the ones that target an impl block. Lang items are now resolved during type inference - this means that `str` completion now works. Fixes #1139.

|\ | | | | | | | | | | | | | | | | | | | | 1138: Add L_DOLLAR and R_DOLLAR r=matklad a=edwin0cheng As discussion in issue https://github.com/rust-analyzer/rust-analyzer/issues/1132 and PR #1125 , this PR add 2 `Syntax::Kind` : `L_DOLLAR` and `R_DOLLAR` for representing `Delimiter::None` in mbe and proc_marco. By design, It should not affect the final syntax tree, and will be discard in `TreeSink`. My original idea is handling these 2 tokens case by case, but i found that they will appear in every place in the parser (imagine `tt` matcher). So this PR only handle it in `Parser::do_bump` and `Parser::start`, although It will not fix the `expr` matcher executing order problem in original idea.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1034: HIR diagnostics API r=matklad a=matklad This PR introduces diagnostics API for HIR, so we can now start issuing errors and warnings! Here are requirements that this solution aims to fulfill: * structured diagnostics: rather than immediately rendering error to string, we provide a well-typed blob of data with error-description. These data is used by IDE to provide fixes * open set diagnostics: there's no single enum with all possible diagnostics, which hopefully should result in better modularity The `Diagnostic` trait describes "a diagnostic", which can be downcast to a specific diagnostic kind. Diagnostics are expressed in terms of macro-expanded syntax tree: they store pointers to syntax nodes. Diagnostics are self-contained: you don't need any context, besides `db`, to fully understand the meaning of a diagnostic. Because diagnostics are tied to the source, we can't store them in salsa. So subsystems like type-checking produce subsystem-local diagnostic (which is a closed `enum`), which is expressed in therms of subsystem IR. A separate step converts these proto-diagnostics into `Diagnostic`, by merging them with source-maps. Note that this PR stresses type-system quite a bit: we now type-check every function in open files to compute errors!
