Is it possible to cache the index results? #22

Closed rwols closed 1 month ago

rwols commented 3 years ago

It looks like rust-analyzer always starts to re-index the entire project anytime I start it. This can take quite a while. Is there a way to cache this index on disk so that it doesn't do that?

Might need an issue in the rust-analyzer repo. Though I'm no rust expert.

I'll just note that VSCode extension also doesn't seem to be doing any caching. Restarting VSCode reindexes the project.

This is unfortunately by design. The indexing is done by cargo metadata and there is a local level of caching from cargo's end, typically with the dependencies so the next time it is faster. However rust-analyzer still needs to build its own data in memory so it knows the project structure and data. Any improvement there would need to be within the server.

Already here I guess https://github.com/rust-analyzer/rust-analyzer/issues/4712

Not something we would can handle on the package side anyway.
