[Bug]: Could you document something about the state of moved-from hash maps?

[inazarenko]

Describe the issue

I couldn't find any documentation as to which methods, if any, are safe to call on a moved-from flat_hash_map.

I assume Abseil follows the STL convention that "moved-from objects shall be placed in a valid but unspecified state".

Does it mean that, at a minimum, clear() on such a container is safe to call and will work as expected (resulting in an empty container)? Or perhaps it's only safe to call operator=(/* empty map */T{})?

Empirically, it seems that calling size() is not safe, at least in ASAN'd code:

Steps to reproduce the problem

This is a documentation problem.

What version of Abseil are you using?

Example uses 20250127, but the documentation question applies to all recent versions.

What operating system and version are you using?

N/A

What compiler and version are you using?
