devenv is really nice.

devenv brings modularity to development shells.

For example, you could configure your devenv module for the shell you want (which env vars you want set, which packages you want available, etc.), and then re-use this module in other shells.

As such, one of the nice things devenv provides is modules with the compilers/lsp/etc. for different languages, so getting a rust environment is about as simple as `languages.rust.enable = true;`.

I haven't explored using the services/processes aspect of it, but it's got support for things like that to. -- I saw it put somewhere: "oh, like docker-compose, but you can compose the configuration".
