The tweet text, the user name, and the number of favorites. ![]() Since decoding large objects is inherently allocation heavy, it may beīeneficial to define a smaller msgspec.Struct type that only has the fieldsįor example, say you’re interested in decoding some JSON from the Twitter API.Ī Tweet object has many nested fields on it - perhaps you only care about When decoding large inputs, sometimes you’re only interested in a few specificįields. This can be done byĬonfiguring omit_defaults=True as part of the Struct definition Omittingĭefaults reduces the size of the encoded message, and often also improvesĮncoding and decoding performance (since there’s less work to do).įor more information, see Omitting Default Values. To omit default values from the encoded message. On the decoding end (making serializing them redundant), it may be beneficial Over other types like dict/ dataclasses/… Avoid Encoding Default Values #īy default, msgspec encodes all fields in a Struct type, including optionalįields (those configured with a default value). If you have data with a known schema, we recommendĭefining a msgspec.Struct type (or types) for your schema and preferring that They’re fast to encode/decode and fast to use. Structs are msgspec’s native way of expressing user-defined types. ![]() decode ( data ) # reuse multiple times Use Structs # Decoder ( list ) # Create once > for data in input_buffers. ![]()
