Hi There
I am doing some unit testing at the moment, and the majority of the leg work
involves taking two objects (expected vs actual) and verifying that their
properties are equal. The objects that I am testing and their properties are
diverse, including enums, basic system types, arrays and nested types.
The objects themselves were not written by me, and do not have any overrides
for equals, compare ... etc.

I have a 3rd party unmanged .dll. This has functions that will look up
information and fill a C string passed to it with data. I want to use this
data in .NET classes after it has been filled and I am programming in C++. I
believe that I should use pinvoke, but I see a problem that I can't figure
how to get around. I don't think I can declare the string I want as a String
class since when I pass it to unmanged function it is not yet...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
