2023-03-10 r/5906 feat(tvix/store): add blobreaderFlorian Klink2-0/+386
A BlobReader can be used to read a blob, which might consist out of multiple chunks. Chunks are fetched from a ChunkService.

2023-01-31 r/5794 feat(tvix/store): add write_nar functionFlorian Klink5-0/+351
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.
