989: Implement naive version of fill_struct_fields assist r=matklad a=yanchith
Fixes#964
This implements the `fill_struct_fields` assist. Currently only works for named struct fields, but not for tuple structs, because we seem to be missing a `TupleStructLit` (akin to `StructLit`, but for tuple structs). I am happy to implement `TupleStructLit` parsing given some guidance (provided it's really missing) and make the assist work for tuple structs as well. Could do so either in this PR, or another one 🙂
Sorry if I missed something important, this is my first PR for Rust Analyzer.
Btw is there any way to run the assists in emacs?
UPDATE: I just realized that parsing `TupleStructLit` would be quite difficult as it it really similar, if not identical to a function call...

Asymptotically computing a set difference is faster but in the average
case we won't have more than ~10 functions. Also prefer not using hash
sets as these may yield nondeterministic results.
762: "Dumb" auto import assist r=matklad a=eulerdisk
This adds a new assist to "add xxx::yyy to the current file" when the cursor is on a PATH. It manages correctly nested imports,`self` keyword and creates new nested imports if necessary. [See the tests]
It doesn't use name resolution so in that sense is 'dumb', but I have plans to do that. That in the future will be useful to auto import trait names in autocompletion for example.
It can easily be extended to provide multiple actions to select in which scope to import. That's another thing I plan to do.
@matklad I copied some indentation code from `ide_light`, I don't know at the moment if/how you want to refactor that code. This assist was meant to be in `ide_light`.

This fixes#713.
If the block before the statement we want to use introduce var on, had empty
lines these empty lines would also be added between the let-statement and
the current line where the new variable is used.
This fixes that by trimming excess newlines from the start of the indent chunk
and simply adding a single newline (when the chunk had newlines) between the
let-statement and the current statement. If there were no newlines this
matches the previous behaviour.
