This module provides a PathInfoService implementation that signs narinfos

Structs

BigtableParameterscloud

Represents configuration of BigtablePathInfoService. This currently conflates both connect parameters and data model/client behaviour parameters.

BigtablePathInfoServicecloud

Provides a PathInfoService implementation using Bigtable as an underlying K/V store.

CachePathInfoService

Asks near first, if not found, asks far. If found in there, returns it, and inserts it into near. There is no negative cache. Inserts and listings are not implemented for now.

CachePathInfoServiceConfig

GRPCPathInfoService

Connects to a (remote) snix-store PathInfoService over gRPC.

GRPCPathInfoServiceConfig

KeyFileSigningPathInfoServiceConfig

ServiceBuilder implementation that builds a SigningPathInfoService that signs narinfos using a keyfile. The keyfile is parsed using parse_keypair, the expected format is the nix one (nix-store --generate-binary-cache-key for more informations).

LruPathInfoService

LruPathInfoServiceConfig

NixHTTPPathInfoService

NixHTTPPathInfoService acts as a bridge in between the Nix HTTP Binary cache protocol provided by Nix binary caches such as cache.nixos.org, and the Snix Store Model. It implements the PathInfoService trait in an interesting way: Every PathInfoService::get fetches the .narinfo and referred NAR file, inserting components into a BlobService and DirectoryService, then returning a PathInfo struct with the root.

NixHTTPPathInfoServiceConfig

RedbPathInfoService

PathInfoService implementation using redb under the hood. redb stores all of its data in a single file with a K/V pointing from a path’s output hash to its corresponding protobuf-encoded PathInfo.

RedbPathInfoServiceConfig

SigningPathInfoService

PathInfoService that wraps around an inner PathInfoService and when put is called it extracts the underlying narinfo and signs it using a SigningKey. For the moment only the ed25519::signature::Signered25519::Signature is available using a keyfile (see KeyFileSigningPathInfoServiceConfig for more informations). However the implementation is generic (see nix_compat::narinfo::SigningKey documentation).

Traits

PathInfoService

The base trait all PathInfo services need to implement.

Functions

from_addr

Constructs a new instance of a PathInfoService from an URI.

register_pathinfo_services 🔒

Registers the builtin PathInfoService implementations with the registry
