Renaming import, cause it to rename in the cached source file as well

[ariaandika]

rust-analyzer version: from rust-analyzer -V: rust-analyzer 0.3.1975-standalone, from nvim mason installed version 2024-05-27

rustc version: rustc 1.78.0 (9b00956e5 2024-04-29)

editor or extension: nvim --version: NVIM v0.10.0

relevant settings: RUSTC_WRAPPER=sccache

step to reproduce:
cargo init

cargo add axum

use axum::response::Html;

fn main() {
    let app = Html("awd");
}

then use "rename" (F2), in use axum::response::Html

use axum::response::Html as HtmlRespone;

fn main() {
    let app = HtmlRespone("awd");
}

rm -rf ./target/, because its not affect this project that use source in ./target/, instead its affect other new project that uses cache in ~/.cargo/registry/src

cargo build

error: could not compile `axum` (lib) due to 2 previous errors
warning: build failed, waiting for other jobs to finish...

the source file in cache renamed

also when i 'write all' in neovim, it shows that it writen file inside ~/.cargo directory

I hit the same issue with Emacs + eglot + rust-analyzer (71a816a90 2024-05-26)

use axum::{
    //...
    Router,
};

renaming Router to AxumRouter resulted in

use axum::{
    //...
    Router as AxumRouter,
};

with the unexpected side effect of also renaming everything in ~/.cargo/registry/src/index.crates.io-6f17d22bba15001f/axum-0.7.5
