+///
+/// The following URIs are supported:
+/// - `memory:`
+///   Uses a in-memory implementation.
+/// - `sled:`
+///   Uses a in-memory sled implementation.
+/// - `sled:///absolute/path/to/somewhere`
+///   Uses sled, using a path on the disk for persistency. Can be only opened
+///   from one process at the same time.
+/// - `grpc+unix:///absolute/path/to/somewhere`
+///   Connects to a local tvix-store gRPC service via Unix socket.
+/// - `grpc+http://host:port`, `grpc+https://host:port`
+///    Connects to a (remote) tvix-store gRPC service.
+///
+/// As the [PathInfoService] needs to talk to [BlobService] and [DirectoryService],
+/// these also need to be passed in.
