Schemas

Schemas used within langgraph_graphs.

Note: These schemas may need to conform to Protocols imposed by backend services.

Generally shouldn't be depended upon in backend (backend should prefer Protocols).

FullBasicGraphState

Bases: FullGraphState

FullGraphState

Bases: BaseModel

General FullGraphState that graphs should inherit from.

This is the general state that e.g. the backend can handle saving and loading between runs.

Note: Graphs using this don't have to use all the fields.

Combine two dictionaries, with right taking precedence over left.
