rust-analyzer silently download dependencies

[Yuuki1578]

Does the rust-analyzer now need some dependencies to work with? When i use rust-analyzer at August 2024 or later that (before october, i dont know the version), it work just fine without internet connection. I use it now without internet connection and the hover output from editor looks like this:

I know that the String type is included in the prelude, but somehow rust-analyzer is unable to find the type.

And when i turn the internet connection on and restart the LSP inside the editor, rust-analyzer will download extra dependecies, like:

platform: Termux aarch64 android

rust-analyzer version: 0.0.0

rustc version: rustc 1.82.0 (f6e511eec 2024-10-15) (built from a source tarball)

editor or extension: Helix

code snippet to reproduce:

rust-analyzer # invoked by helix

I believe what changed is in rust, not in r-a, that stdlib has a proper Cargo project now so rust-analyzer can index it properly, which means it's downloading std's dependencies.

We also run rustup component add rust-src if it's not available. I don't think it's such a big deal.
