Crate nodedb_client 

NodeDB client SDK: the NodeDb trait, the NodeDbRemote client (native MessagePack via TLS, opt-in via the native feature; pgwire compatibility via the remote feature), and capability negotiation.

For embedded use, depend on nodedb-lite directly. For server use, enable the native feature and connect to a NodeDB Origin node via its native protocol — pgwire compatibility (remote) is provided so existing PostgreSQL drivers can connect for read-mostly workloads, but it is not the long-term ORM target.

Modules

capabilities

Capabilities newtype for typed capability bit-test accessors.

traits

The NodeDb trait: unified query interface for both Origin and Lite.

Structs

Document

A CRDT-backed document. The primary data unit across all NodeDB engines.

EdgeFilter

Edge filter for graph traversal. Constrains which edges are followed during BFS/DFS.

EdgeId

Identifies a graph edge. Returned by graph_insert_edge.

NodeDbError

Public error type returned by all NodeDb trait methods.

NodeId

Identifies a graph node. Separate from DocumentId because graph nodes can exist independently of documents (e.g., concept nodes in a knowledge graph).

QueryResult

Result of a SQL query or multi-modal query.

SearchResult

Result of a k-NN vector search.

SubGraph

Result of a graph traversal (BFS/DFS).

Enums

MetadataFilter

Metadata filter for vector search. Applied as a pre-filter (Roaring bitmap) or post-filter depending on selectivity.

Value

A dynamic value that can represent any field type in a document or any parameter in a SQL query.

Type Aliases

NodeDbResult

Result alias for NodeDb operations.
