Struct.update populates scalar, boolean, null, nested dict, and list fields with automatic Value and ListValue wrapping, while assigning unsupported types raises ValueError.
Struct helper methods get_or_create_struct and get_or_create_list instantiate child containers in-place and support append, extend, and index mutation.
Any.Pack serializes arbitrary protobuf messages including Struct with default type.googleapis.com URL prefix or explicit custom prefix, and TypeName extracts the clean message name.
Any.Is verifies descriptor matching, while Any.Unpack deserializes the payload into matching message instances and safely returns False without modifying destination on type mismatch.
MessageToDict and ParseDict round-trip Struct directly as native dictionaries and Any containers with @type discriminator metadata.
