Description

I frequently use autocomplete on methods/functions. The scoring is a little weird though.

99% of the time I want cl to complete to clone but it completes to clamp. I get why, but this gets annoying.

I'd be happy to implement a scoring system that suggest relevant tokens instead of alphabetically.

I was thinking of scraping the top rust projects, doing a frequency analysis of tokens, and then baking that into a scoring hashmap which RA can use to provide nicer suggestions.

Research direction

The issue names no files, tests, or entry points. Start by locating rust-analyzer's autocomplete scoring implementation, then evaluate how token-frequency data from top Rust projects could be incorporated; done means commonly used completions such as clone rank ahead of clamp for cl.
