Make the trait public, so consumers can use it. Also, implement it for node::Node, so we can later use this to access the name from all three if we don't care about the enum type.

//tvix/store
This contains the code hosting the tvix-store.
For the local store, Nix realizes files on the filesystem in /nix/store
(and
maintains some metadata in a SQLite database). For "remote stores", it
communicates this metadata in NAR (Nix ARchive) and NARInfo format.
Compared to the Nix model, tvix-store
stores data on a much more granular
level than that, which provides more deduplication possibilities, and more
granular copying.
However, enough information is preserved to still be able to render NAR and
NARInfo (handled by //tvix/nar-bridge
).
More Information
Check the protos/
subfolder for the definition of the exact RPC methods and
messages.
Interacting with the GRPC service manually
The shell environment in //tvix
provides evans
, which is an interactive
REPL-based gPRC client.
You can use it to connect to a tvix-store
and call the various RPC methods.
$ cargo run &
$ evans --host localhost --port 8000 -r repl

Thanks to tvix-store
providing gRPC Server Reflection (with reflection
feature), you don't need to point evans
to the .proto
files.
