This allows us to select a string or portions of it and try parsing it as rust
syntax. This is mostly helpful when developing tests where the test
itself contains some rust syntax as a string.
Previously when using the file based syntax tree, it would not update until a
change had been made in the new file. Now we automatically update the syntax
tree to match the current file.
This enables the client to use a command to either show the live-updating
version of the syntax tree for the current file. Or optionally when a selected
range is provided, we then provide a snapshot of the syntax tree for the range.
917: Trait tests r=flodiebold a=flodiebold
This adds a bunch of basic tests for trait functionality, just to outline what seems like the first goals for that ;)
It also changes the display of `Ty::Unknown` to `{unknown}`, since `[unknown]` could be confused with a slice, and fixes an error in the emacs runnables code.

908: Enable markup for hover on expressions which resolve using type_of r=matklad a=vipentti
This adds highlighting when hovering over items which are resolved using
`type_of`.
This adds basic highlighting, discussed in #904.

915: Bring BodySyntaxMapping in line with other source-map instances r=flodiebold a=matklad
* rename to SourceMap
* don't store the actual body inline, just return a pair
r? @flodiebold

906: Add support for goto definition and hover for struct fields r=matklad a=vipentti
This works partially towards fixing #512

900: Add new trait ast::TypeAscriptionOwner r=vipentti a=vipentti
This trait should be implemented for nodes which have an ascribed type,
e.g. thing : Type. Such as let, const, static, param, named struct fields.
In addition, we update some places where previously we used node + node.type_ref() with `TypeAscriptionOwner` in the trait bounds.

901: Add basic support for showing fn signature when hovering r=matklad a=vipentti
This adds basic support for displaying function signature when hovering over a usage of a function.
Additionally refactored `hover` to return `HoverResult` to ease with testing and in general to be more robust.

903: Work around for issue in vscode reporting a failure in request r=matklad a=vipentti
vscode would report "A request has failed" when it got "Content modified"
message and this would cause a pop-up to appear. This works around the issue by
returning an "empty" response that vscode can ignore.

vscode would report "A request has failed" when it got "Content modified"
message and this would cause a pop-up to appear. This works around the issue by
returning an "empty" response that vscode can ignore.
This replaces places where we would use node + node.type_ref() with things that
have an ascribed type, with using the TypeAscriptionOwner as the trait bound so
we can simply pass the node.
