* Use RUSTFLAGS to set the optimization level
Cargo has a [quirk]() in how configuration settings are propagated when `cargo test` runs: local code respect the settings in `[profile.test]` but all dependencies use the `[profile.dev]` settings. Here we force `opt-level=3` for all dependencies.
* Remove unused profile settings
* Maybe like this?
* Turn off incremental compilation
* Remove colors; try again with overflow-checks on
* Use quiet CI machine
* Turn overflow checking back on
* Be explicit about what options we use
* Remove "quiet machine" override
* check if it was the file
* collect tog files
* some debug
* some more debug
* some even more debug
* upload all the logs
* change cache max size
* test with max cache size overflow
* verbose for all cargo jobs
* lower max cache size
* Rust nightly and beta test runs reintroduced
* artifacts:when: always, coz on_success is default
* sccache full log
* normal artifacts name, big cache size
* add file to test the compilation again
* another way of getting artifacts
* per-job cache
* data race tests
* is it needed to clean the working folder?
* return to common cache dir
* do not pass logs between jobs
* typo
* avoid artifacts conflict
* colored logs
* always colored logs
* proper stages
* more proper stages skip-ci
* more proper stages [skip-ci]
* shouldn't skip ci
* tests splitted, phase 1
* typo
* fix wrong launch commands
* typos
* rearrangements
* use `nproc` function for threads
* use nproc for threads
* let theads be auto, build-andriod no more in regular run
* split val chain and cargo check
* renamed some files
* wrong phase
* check rust files before test jobs
* lint error
* rust files modivied var
* test except changes
* add rust_changes except
* lint error
* fixes
* .gitlab-ci.yml can't be excluded
* pipeline shouldn't start
* pipeline must go
* pipeline must go 2
* pipeline must go 3
* pipeline must go 4
* pipeline must go 5
* pipeline must go 6
* pipeline must go 7
* pipeline must not go 1
* pipeline must go 8
* avoid skippng tests yet, reintroducing them after the caching
* test theory
* parallelized cargo check with combusting helicopters
* less uploads
* alias for cargo checks
* nice template
