enum_map class

[jlwoolf]

I thought this could be a potential branch for the magic_enum library. It is a simple map data structure that utilizes some of the magic_enum functions to map every enum entry to a unique value.

For updating, I didn't forget about this PR, now I'm preparing a new release 0.8.0, and this PR will be included in the next release 0.8.1

This can be made constexpr, like I suggest here

So I think this needs an upgrade

[Neargye]

it is better to keep this class in a separate header. And I thing need all map-api begin/end find etc, https://github.com/Neargye/magic_enum/issues/150 was just a concept idea and not advice for implementation

@jlwoolf @schaumb Can i help with that pr to make it mergeable for Neargye?

[jlwoolf]

@florianbecker I haven't really had the time to work on this much, so if you'd like to continue it, by all means go ahead. I can close this pull request if you'd like to open another with the improvements/fixes, or add you as a contributor to the fork.

Hi!

I started an another PR. I implemented already array bitset set and flat_set to namespace magic_enum::containers.

I thought I has time to implement the multiset map and flat_map too.

The array class is semantically equal to this PR.
