How far are we from `@dataclass`

[junrushao]

• Init: generates __init__ (we implemented some of the logics in @c_class)

  • flag init=True in @dataclass
  • flag init=True in dataclasses.field
  • run __post_init__ if presents
  • default=MISSING, default_factory=MISSING in dataclasses.field
  • InitVar
  • ClassVar
  • kw_only=False in @dataclass
  • kw_only=MISSING in dataclasses.field
  • dataclasses.KW_ONLY

• Repr: generates __repr__

  • flag repr=True in @dataclass
  • flag repr=True in dataclasses.field

• Copy: Generate copy interface

  • def __copy__(self)
  • def __deepcopy__(self, memo)
  • def __replace__(self, **changes) and dataclasses.replace

• Comparison

  • eq=True in @dataclass: generates __eq__ and __ne__
  • order=False in @dataclass: generates __lt__, __le__, __gt__, and __ge__,
  • compare=True in dataclasses.field

• Mutability and extra slots:

  • slots: feat: Restrict __slots__=() for subclasses of tvm_ffi.Object by default #364
  • frozen=False: mutability
  • weakref_slot=False

• Hashing

  • unsafe_hash=False
  • hash=None

Misc

• match_args=True in @dataclass
• metadata=None in dataclasses.field
• doc=None in dataclasses.field
• dataclasses.fields
• dataclasses.asdict
• dataclasses.astuple
• dataclasses.make_dataclass
• dataclasses.is_dataclass
