SlyMastodon.serialization#

Extended support for deserialization of Python types from JSON

Functions

convert_from_json(cls, value[, typevars_, ...])

Convert a json value to a T instance.

Classes

DataclassJsonMixin()

Mixin for dataclasses to add a from_json method
SlyMastodon.serialization.convert_from_json(cls: type[T], value: int | float | bool | str | None | Sequence[JsonTypeCo] | Mapping[str, JsonTypeCo], typevars_: dict[str, type] | None = None, parent: type | None = None) → T#

Convert a json value to a T instance.

May not round-trip, especially if a member of T is a union of multiple types with the same representation (e.g. set | list, dict | dataclass)

Fails if representation was different than what was expected. Additional supported types different from json:

  • datetime.datetime

  • enum.Enum

  • set[T], tuple[T, …]

  • dataclasses (assuming all members are convertable)

  • TypeAliases

  • Generic TypeAliases and dataclasses
