This allows to colorize these variables/parameters when used in call expression. 6310: Rewrite algo::diff to support insertion and deletion r=matklad a=Veykril This in turn also makes `algo::diff` generate finer diffs(maybe even minimal diffs?) as insertions and deletions aren't always represented as as replacements of parent nodes now. Required for #6287 to go on. Co-authored-by: GrayJack <[email protected]> Co-authored-by: Lukas Wirth <[email protected]>

|/ | | | | | | | Declaration names sounds like a name of declaration -- something you can use for analysis. It empathically isn't, and is just a label displayed in various UI. It's important not to confuse the two, least we accidentally mix semantics with UI (I believe, there's already a case of this in the FamousDefs at least).

After a third try, it finally works. Boy, it appeared tougher than it seemed. Initially I thought like "Ha, `rustc` already tells us where idents are named incorrectly. It shouldn't be that hard, should it?". Well, the problems with the information provided by `rustc` appeared shortly: - `rustc` warnings are `flycheck` warnings, which are slightly aside from our diagnostics with fixes. When we map flycheck diagnostic to LSP, we can convert it into a fix, but only if it's marked as `Applicability::MachineApplicable`. Name case fix is marked `Applicability::MaybeIncorrect`, and for a reason: it only suggest to rename symbol under cursor, without tracking any references. - Warning spawned by `rustc` are identified by string labels rather than enum. It means that if one day the diagnostic will be renamed in `rustc`, `rust-analyzer` code will still compile, but won't find the required diagnostic by name anymore. If by chance this will happen when some unlucky guy will decide to create their first pull request, they'll be confused by suddenly failing tests (likely) not related to their changes. - Even if we'll try to build fixes atop of `rustc` warnings, we'll have to do it in the `rust_analyzer::diagnostics::to_proto` module, which is far less convenient for that matter than `ide` crate. That's why I decided that it's worth a separate `rust-analyzer` diagnostic, which will implement `DiagnosticWithFix` trait. After that, I discovered that currently `hir_ty::diagnostics` only check `DefWithBody` types, like function bodies. I had to add support for diagnostics which look at any `ModuleDef`. And of course, since I'd added a lot of new functionality, it required extensive testing. That explains why the diff is so big for a (looking) relatively small feature. I hope that this PR doesn't only add a small feature, but also creates a base for building another features. ## Example: ![case_quick_fix](https://user-images.githubusercontent.com/12111581/95008475-e07ee780-0622-11eb-9978-62a9ea0e7782.gif) P.S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently a method only has defaultness if it is a provided trait method, but this will change when specialisation is available and may need to become a concept known to hir. I opted to go for a 'fewest changes' approach given specialisation is still under development.

Here's some concern about implementation detail: - Chalk doesn't support generator type yet. - Adding generator type as a brand new type (ctor) can be complex and need to *re-introduced* builtin impls. (Like how we implement closures before native closure support of chalk, which is already removed in #5401 ) - The output type of async block should be known after type inference of the whole body. - We cannot directly get the type from source like return-positon-impl-trait. But we still need to provide trait bounds when chalk asking for `opaque_ty_data`. - During the inference, the output type of async block can be temporary unknown and participate the later inference. `let a = async { None }; let _: i32 = a.await.unwrap();` So in this PR, the type of async blocks is inferred as an opaque type parameterized by the `Future::Output` type it should be, like what we do with closure type. And it really works now. Well, I still have some questions: - The bounds `AsyncBlockImplType<T>: Future<Output = T>` is currently generated in `opaque_ty_data`. I'm not sure if we should put this code here. - Type of async block is now rendered as `impl Future<Output = OutputType>`. Do we need to special display to hint that it's a async block? Note that closure type has its special format, instead of `impl Fn(..) -> ..` or function type. Co-authored-by: oxalica <[email protected]>

| | | | | | | | | | | | `hir` should know nothing about URLs, markdown and html.
