Hello there, I have been resourching a way for me to detect which version of rust I have installed in my system, the problem is that I want to know the version of the language, not of cargo or rustc.

I notice that:

```shell
rustup update                                                   
info: syncing channel updates for 'stable-x86_64-unknown-linux-gnu'
info: syncing channel updates for 'beta-x86_64-unknown-linux-gnu'
info: checking for self-updates

  stable-x86_64-unknown-linux-gnu unchanged - rustc 1.56.1 (59eed8a2a 2021-11-01)
    beta-x86_64-unknown-linux-gnu unchanged - rustc 1.57.0-beta.3 (708d57e28 2021-11-01)

```

which does infact reflect on the actual version of the rust language in the github

yes, that's the same version. Simplest way to check IMO would be to run `rustc -V` or maybe `rustc +stable -V` if you're specifying a non-default toolchain
