new_schema_validator()

@classmethod
def new_schema_validator(

    schema_type_path: [SchemaTypePath](schematypepath.md?sid=pydantic_plugin_schematypepath),
    schema_kind: SchemaKind,
    config: CoreConfig | None,
    plugin_settings: dict[str, object]
) - > tuple[ValidatePythonHandlerProtocol | None, ValidateJsonHandlerProtocol | None, ValidateStringsHandlerProtocol | None]

This method is called for each plugin every time a new [SchemaValidator][pydantic_core.SchemaValidator] is created. It should return an event handler for each of the three validation methods, or None if the plugin does not implement that method.
