notes for when I'm setting up a new development environment
I assume you have already installed mysql via brew (so you can install the diesel-cli with cargo).
brew install rustup-init rustup-init rustup update rustup default stable
in case you need to use the `nightly` builds, take into account that not all have the necessary components to successfully compile your projects. take a look at the link below (select the processor architecture that you need) and install the toolchain you want with `rustup toolchain install nightly-2022-01-06`, for example, if you want the components present in the `2022-01-06` nightly build.
