* Document `hir::Function::ret_type`Arnaud2021-01-041-0/+4
| | | | | This adds documentation for the newly added function. It might be a bit too detailed, but I like it that way :)
* Make it possible to retrieve `hir::Function`'s return typeArnaud2021-01-041-0/+23
| | | | | | This is done by adding a `ret_type` method to `hir::Function`. I followed `assoc_fn_params` convention by creating a new `RetType` type, that contains the actual return type accessible via a `ty` method.

Very rough initial version just to work out where I needed to wire everything up. @matklad would you be happy merging a hir visualiser of some kind? If so, do you have any thoughts on what you'd like it show, and how? I've spent very little time on this thus far, so I'm fine with throwing away the contents of this PR, but I want to avoid taking the time to make this more polished/interactive/useful only to discover that no-one else has any interest in this functionality. ![image](https://user-images.githubusercontent.com/1974256/103236081-bb58f700-493b-11eb-9d12-55ae1b870f8f.png) Co-authored-by: Phil Ellison <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | special cased In #6901 some special case handling for proc-macros was introduced to prevent panicing as they have no AST. Now the new HasSource::source method is used that returns an option. Generally this was a pretty trivial change, the only thing of much interest is that `hir::MacroDef` now implements `TryToNav` not `ToNav` as this allows us to handle `HasSource::source` now returning an option.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 6964: Add full pattern completions for Struct and Variant patterns r=matklad a=Veykril Just gonna call it full pattern completion as pattern completion is already implemented in a sense by showing idents in pattern position. What this does is basically complete struct and variant patterns where applicable(function params, let statements and refutable pattern locations). This does not replace just completing the corresponding idents of the structs and variants, instead two completions are shown for these, a completion for the ident itself and a completion for the pattern(if the pattern make sense to be used that is). I figured in some cases one would rather type out the pattern manually if it has a lot of fields but you only care about one since this completion would cause one more work in the end since you would have to delete all the extra matched fields again. These completions are tagged as `CompletionKind::Snippet`, not sure if that is the right one here. <details> <summary>some gifs</summary> ![dx2lxgzhj3](https://user-images.githubusercontent.com/3757771/102719967-6987ef80-42f1-11eb-8ae0-8aff53777860.gif) ![EP2E7sJLkB](https://user-images.githubusercontent.com/3757771/102785777-c7264580-439e-11eb-8a64-f142e19fb65b.gif) ![JMNHHWknr9](https://user-images.githubusercontent.com/3757771/102785796-d1e0da80-439e-11eb-934b-218ada31b51c.gif) </details> Co-authored-by: Lukas Wirth <[email protected]>

|\ \ | |/ |/| | | | | | | | | | | 6921: Higher-ranked trait bounds for where clauses r=flodiebold a=Veykril There is a slight problem with this which is also noted in a FIXME now but `LifetimeParameters` of these ForLifetime where clauses allocate the lifetimes in the corresponding arena as if they were lifetimes of the item itself and not just the clause they belong to. I wasn't entirely sure what I could do about this but given nothing really uses lifetimes like that currently I figured it might be fine? Open to suggestions for that problem.

|/ | | | | | | | 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.
