A Msgspec inspired dataclass library Made for CPython, Python and Cython.
- The code from msgspec is forked and is being carefully optimized.
- Fields are subclassable making it very easy to customize and manipulate
__post_new__function upon dataclass creation for tools like sqlalchemy__subclass_init__or a metaclass can be used when making your own custom base- Only core functionality is provided meaning that json or other serlizers will have to be written on your own. With everything being written in Cython that should make it very easy to configure and with a Cython port being included you'll be more than ready for such a task.
- Code can be compiled on it's own or with Cython (I hope for something simillar to what numpy does)
- When msgspec itself doesn't do exactly what you want
- When you want to merge an sql library like sqlalchemy or Peewee3 to it directly (Might look into how Peewee3 makes dataclasses since it's a dataclass-like sql-library written in Cython) this can be easily frustrating when you don't have any control over 2 libraries
- When you need customization over the
__new__function under__post_new__ - Making a quick/dirty dataclass-model without the code-bloat
- When you do not need validators which can be slow on initialization.
- Were currently stuck on the integration portion of this library were functions like
__new____init_subclass__or others should be used. Finding a way to hack in acdef classDefinition on any of these requires new proposals to the Cython Developers on how I can get this kind of dataclass integrated in both Cython and Python. - msgspec & attrs support (Maybe another extension like the one attrs added to msgspec)
- Propose for Cython to allow cdef metaclasses under a new directive/wrapper which
will allow heapstruct to become it's own cython library thus preventing it from being
limited to python items such as giving
__init_subclass__and__new__support I will be drawing out concept templates for how this can be approched in C.
