Remove client side proc-macro version check
The server already verifies versions due to ABI picking now so there shouldn't be a need for the client side check anymore
internal: Coalesce adjacent Indels
Originally part of working on a structured snippet API (since sometimes the `$` bit of snippets would be broken off and would lead to it not being recognized), though since this is a pretty separate change, I thought it would make sense to put it into it's own PR.
The implementation is relatively straight forward and not overly optimized, though it's pretty low hanging fruit to optimize it when need be.
MIR episode 3
This PR adds lowering for try operator and overloaded dereference, and adds evaluating support for function pointers and trait objects. It also adds a flag to `analysis-stats` to show percentage of functions that it fails to emit mir for them, which is currently `20%` (which is somehow lying, as most of the supported `80%` are tests). The most offenders are closure (1975 items) and overloaded index (415 items). I will try to add overloaded index before monday to have it in this PR, and tackle the closure in the next episode.
internal: Bump chalk
This release fixes a problem around GATs (rust-lang/chalk#790). While a regression test is added in chalk's own test suite, I also added one in ours so that we can catch regressions when we move away from chalk.
Fixes#14164
feat: show only missing variant suggestion for enums in patterns completion and bump them in list too
Fixes#12438
### Points to help in review:
- This PR can be reviewed commit wise, first commit is about bumping enum variant completions up in the list of completions and second commit is about only showing enum variants which are not complete
- I am calculating missing variants in analysis.rs by firstly locating the enum and then comparing each of it's variant's name and checking if arm string already contains that name, this is kinda hacky but I didn't want to implement complete missing_arms assist here as that would have been too bulky to run on each completion cycle ( if we can improve this somehow would appreciate some inputs on it )
