2023-03-10 r/5918 feat(tvix/store): add NARCalculationService trait and implFlorian Klink3-3/+66
This adds a NARCalculationService trait, which will take a root node, and provide a proto::CalculateNarResponse in return. It also adds a NonCachingNARCalculationService implementation, that will simply always render the NAR in memory to calculate the size and sha256, without any caching.

2023-03-10 r/5915 chore(tvix/store): move NAR rendering logic into Renderer structFlorian Klink5-181/+275
This moves the logic rendering NARs to a struct using the previously introduced, more granular BlobService, ChunkService and DirectoryService. Instead of passing them around to the helper functions, they're kept as members of a struct. Remove the async invocations in the nar_renderer tests, there's nothing async in here.

This adds a function that consumes a [proto::node::Node] pointing to the root of a (store) path, and writes the contents in NAR serialization to the passed [std::io::Write]. We need this in various places: - tvix-store's calculate_nar() RPC method needs to render a NAR stream to get the nar hash, which is necessary to give things imported in the store a "NAR-based" store path. - communication with (remote) Nix (via daemon protocol) needs a NAR representation. - Things like nar-bridge, exposing a NAR/NARInfo HTTP interface need a NAR representation.

2023-01-03 r/5572 feat(tvix/store/nixpath): DIGEST_SIZE public, use more constsFlorian Klink1-12/+18
Rename PATH_HASH_SIZE to DIGEST_SIZE. It's a digest, not hash (we don't necessarily have the internal hash state anymore), and the fact it's about (Nix)Paths is already visible from the module name. Also expose ENCODED_DIGEST_SIZE, so we don't need to do the calculation inside from_string() method, and it becomes more clear this is a constant.
