Adam Joseph 947a56c4b6 feat(tvix/eval): builtins.storeDir
Returns the store directory through EvalIO::store_dir.

Note that this is _optional_ in Tvix, as an evaluation can occur in a
context where there simply is no store directory. In those contexts,
`builtins.storeDir` returns `null` in Tvix.

This would only happen in contexts like Tvixbolt (or completely
unrelated use-cases) in practice.

Tvix

For more information about Tvix, contact one of the project owners. We are interested in people who would like to help us review designs, brainstorm and describe requirements that we may not yet have considered.

Rust projects

Some parts of Tvix are written in Rust. To simplify the dependency management on the Nix side of these builds, we use crate2nix in a single Rust workspace in //tvix to maintain the Nix build configuration.

When making changes to Cargo dependency configuration in any of the Rust projects under //tvix, be sure to run crate2nix generate in //tvix itself and commit the changes to the generated Cargo.nix file.

crate2nix is available via direnv inside of depot, or can be built from the third_party.nixpkgs.crate2nix attribute of depot. Make sure to build it from depot to avoid generating files with a different version that might have different output.

License structure

All code implemented for Tvix is licensed under the GPL-3.0, with the exception of the protocol buffer definitions used for communication between services which are available under a more permissive license (MIT).

The idea behind this structure is that any direct usage of our code (e.g. linking to it, embedding the evaluator, etc.) will fall under the terms of the GPL3, but users are free to implement their own components speaking these protocols under the terms of the MIT license.
