[Bug 2139514] [NEW] rustanalyzer cannot find libstd sources for rust-1.82-src

[Dmitry]

Public bug reported:

Hello!

Looks like there is no sources at the path where rustanalyzer searches.
I believe that it searches at sysroot/lib/rustlib where sysroot is
reported by rustc command 'rustc --print sysroot'. It is /usr for
default rust-all package and /usr/lib/rust-1.xx for rust-1.xx-all
packages.

There is no src directory for rust-1.82-src packages.

$ ls -l /usr/lib/rustlib/
total 12
drwxr-xr-x 2 root root 4096 Jan 31 20:14 etc
drwxr-xr-x 2 root root 4096 Jan 31 20:14 src
drwxr-xr-x 4 root root 4096 Jan 31 20:14 x86_64-unknown-linux-gnu

$ ls -l /usr/lib/rust-1.85/lib/rustlib/
total 12
drwxr-xr-x 2 root root 4096 Jan 30 17:48 etc
drwxr-xr-x 2 root root 4096 Jan 31 20:15 src
drwxr-xr-x 4 root root 4096 Jan 30 17:48 x86_64-unknown-linux-gnu

$ ls -l /usr/lib/rust-1.82/lib/rustlib/
total 8
drwxr-xr-x 2 root root 4096 Jan 30 18:12 etc
drwxr-xr-x 4 root root 4096 Jan 30 18:11 x86_64-unknown-linux-gnu

It is minor issue because there are more up-to-date compilers available
without such problem. For example, rust-1.85-src does not have such
problem.

Thank you.
