We want to make sure we can use bit_cast with suitable vector or sum types like

  • cuda::std::array
  • c-arrays
  • cuda vector types like float2

Unfortunately we cannot use it with the extended floating point vector types, because they are not trivially copyable and also not trivially copy assignable

great to see this extension for bit_cast!
AFAIK cuda vector types like float2 should be already trivially copyable. Please also consider std::pair

They are, I was talking about __half2 and __nv_bfloat162

The issue with std::pair is that it is not triviallly copyable or trivially default constructible

I guess now you can replace the unsafe_bitcast function used in CUB

@miscco
Allow arrays and tuples for bitcast
4f4a739
@miscco
Ensure cuda::std::bit_cast works with vector types
5e3f9e3 
We want to make sure we can use `bit_cast` with suitable vector or sum types like
* `cuda::std::array`
* c-arrays
* cuda vector types like float2

Unfortunately we cannot use it with the extended floating point vector types, because they are not trivially copyable and also not trivially copy assignable
