Dear Kabelo,
For Rust's standard library completion, you might be missing `rust:rust-src`
variant of the package `rust`?

I actually found out about the problem of `rust-analyzer-proc-macro-srv`. I
started working on a patch, and have something that I believe works. You can
try it on my channel for the moment [1]. Please tell if that works for you.
Note that you won't be able to refer to it by it's name, so you might need to
import the module and use the variable name `rust-1.82`. Here is a example of a
manifest working with it.
```rust
(use-modules (guix packages)
(guix profiles)
(gnu packages commencement)
(gnu packages llvm)
(gnu packages rust)
(tuziwo packages rust))
(packages->manifest (list clang
gcc-toolchain-14
pkg-config
rust-1.82
`(,rust-1.82 "cargo")
`(,rust-1.82 "rust-src")
`(,rust-1.82 "tools")
rust-analyzer))
```
That said, the solution I have is not entirely satisfactory. I talked with
Efraim on last Friday (at the Guix Days) and we were trying to find a better
solution [2] to push it upstream. So still digging (when I find time).
I hope this helps.
