The DType API publicly exposes the PyArray_DTypeMeta C struct, which represents DType metaclasses. It also exposes a function for registering user-defined DTypes and a set of slot IDs and function typedefs that users can implement in C to write new DTypes.
The ArrayMethod API allows defining cast and ufunc loops in terms of these new DTypes, in a manner that forbids value-based promotion and abstracts many of the internals of NumPy. We hope the ArrayMethod API is enables sharing low-level loops that work out-of-the-box in NumPy in other projects.
To emphasize what Nathan wrote: this is the culmination of YEARS of work. My gratitude goes out to everyone who took part in meetings (both in-person and virtual), code development & review, NEP & documentation writing, community discussions, etc.: thank you. I cannot wait to see everything your hard work will enable. Stéfan
