2641: Parse const generics r=matklad a=roblabla
Adds very primitive support for parsing const generics (`const IDENT: TY`) so that rust-analyzer stops complaining about the syntax being invalid.

2629: Remove imports from hir r=matklad a=matklad
We only used them to avoid self-confirming completions (`use self::foo`), but that can be handled more locally.

2628: Add macro 2.0 support in parser r=matklad a=edwin0cheng
This PR added a new syntax kind : `MACRO_DEF` and a keyword `MACRO_KW`
there are two syntax for declarative macro 2.0 :
1. Normal : `macro m { ($i:ident) => {} }` , which handle similar to legacy one.
2. Call like: `macro m($i:ident) {}`, it produces a single token tree which have two child token trees : `($i:ident)` and `{}`

Just a few tweaks from the latest clippy. There are a lot more but we should probably tweak our settings.

2592: Add std::ops::Index support for infering r=edwin0cheng a=edwin0cheng
see also #2534
Seem like this can't fix#2534 for this case:
```rust
fn foo3(bar: [usize; 2]) {
let baz = bar[1]; // <--- baz is still unknown ?
println!("{}", baz);
}
```

2311: See through Macros for SignatureHelp r=matklad a=kjeremy
Note: we meed to skip the trivia filter to make sure that
`covers!(call_info_bad_offset)` succeeds otherwise we exit call_info
too early.
Also the test doesn't pass: `FnCallNode::with_node` always detects
a MacroCall which is obviously wrong.

2562: Fix NavigationTarget ranges r=matklad a=edwin0cheng
Fix the issue described in https://github.com/rust-analyzer/rust-analyzer/pull/2544#issuecomment-565572553
This PR change the order for finding `full_range` of `focus_range` in following orders:
1. map both ranges to macro_call
2. map focus range to a token inside macro call, and full range to the whole of macro call
3. map both ranges to the whole of macro call
And fix the corresponding tests and make these tests easily to follow.

When calling a function, argument-position impl Trait is transparent; same for
return-position impl Trait when inside the function. So in these cases, we need
to represent that type not by `Ty::Opaque`, but by a type variable that can be
unified with whatever flows into there.
2559: Add some granularity to syntax highlighting. r=matklad a=omerbenamram
Hi,
I wanted to start using `rust-analyzer` a bit more frequently - one of the main blockers for me so far was the highlighting.
I just discovered it's possible to override the default colors with `ralsp.<something>` setting without waiting for #2061!
However, the current implementation was lumping a bunch of different tokens into `type` and `literal`.
The golden standard IMO is what Clion is currently doing (and is my current daily driver for rust).
Clion allows users to control the coloring for specific literal kinds, and the default is to distinguish between them (numerics get a different color from strings, and special colors for bytestrings).
I've also splitted the builtin types, which are also allowed to be highlighted speratly.
My goal is to match the default experience I'm getting with clion.
The only blockers now I think is that `rust-analyzer` doesn't corrently infer types in some situations, so the highlighting information is incorrect in those cases.
This is what it looks like so far (with colors overriden to match clion's theme):
If there are any other changes you feel is necessary let me know.
I did leave the default colors to match the current behavior, since I'm not familiar with the colors for this theme, I added some random (different) colors in the test to check that it indeed was working.

2552: fix goto definition when inbetween tokens r=matklad a=succcubbus
fixes both goto_definition and goto_type_definition.
before, when running goto between some non-trivia token and an
identifier, goto would be attempted for the non-trivia token.
but this does not make sense for e.g. L_PAREN or COLONCOLON only for
IDENTs.
this resulted in goto actions not working when running them on the first
character of some identifier e.g. for `module::<|>method()` or
`method(<|>parameter)`.
now only IDENTs will be searched for in goto actions, though i'm not sure
if this is correct or if goto should also work for some other token types.
