EASTL version 3.21.23

[grojo-ea]

Updates since the last version.

• removed generic definition of numeric_limits<>
• removed EASTL_CUSTOM_FLOAT_CONSTANTS_REQUIRED & associated functionality
• removed Internal::numeric_limits_base
• added isnan to EASTL when compiled with C++20
• added is_constant_evaluated
• fixed midpoint to behave correctly when passed NaNs
• Add bounds checking assert for array<T, N>::operator[].
• Fixed fixed_vector move constructor with an explicit allocator parameter. It now works with move-only types.
• Add bit_and, bit_or, bit_xor, bit_not and owner_less<void> function objects.
• Use string builtins to improve codegen for string literals operations on string_view and string.
• span is now specialized for static extents so that it doesn't need to store the size at runtime.
• Fixed a bug where calling emplace, emplace_hint, or try_emplace on a string_hash_map would call the underlying hash_map implementation, which caused a crash when string_hash_map would try to free memory it didn't own.
• Use EA_DEPRECATED date based macros if available to guide deprecations.
• Consolidate implementations of CharTypeStringSearch/Find functions in char_traits.h.
• Minor optimization to CharTypeStringRSearch to reduce iteration loop count.
• Fix deque move assignment operator for move only and non-default constructible types.
• Added monadic operations and_then, transform and or_else for optional.
• Fixed value_or for r-value refs to optional.
• Various bitset fixes and improvements:
  • Replace bitset(uint32_t) with bitset(unsigned long long) which matches the standard and means that 64 bit integers can be correctly converted to a bitset. As a result from_uint32() and from_uint64() are now unnecessary (not deprecated).
  • Add to_ulong_checked() with the same behaviour as the standard, ie. throws or asserts if the target type cannot represent all the set bits.
  • Add an extension to the standard, as_uint<T>() / as_ulong(), cast to a unsigned integral that can represent the entire bitset. If the target type cannot represent the entire bitset, then issue a compile error (overload does not exist).
  • Fix implementation for word types smaller than 32 bit. Fixed logic in find_prev(), other iteration functions and conversion to/from bitset functions that did not work for such types.
  • No longer assume sizeof(word_type) == EA_PLATFORM_WORD_SIZE. eg. from_uint64() previously would not copy the entire value into a bitset<N, uint32_t> for N > 32.
  • Now compiles for a word type of unsigned long or unsigned long long where the type is not uint64_t.
  • Add an assert that the word type is an unsigned integral, as these are the only types that are supported and tested.
• Add get<T>(pair<T1, T2>). Make get<I>(pair<T1, T2>) constexpr.
• Fix variant non-member functions get_if(), get(), holds_alternative() and converting constructor and assignment so that they only conditionally compile when the index or type unambiguously refers to a variant alternative.
• any::emplace() now returns a reference.
• lru_cache::emplace() now compiles correctly, forwarding its arguments and returns an pair of iterator and bool indiciating emplace success.
• Made changes to avoid -Wdeprecated-copy-with-user-provided-copy, which manifests for the following reasons:
  • definition of implicit copy assignment operator for class is deprecated because it has a user-provided copy constructor
  • definition of implicit copy constructor for class is deprecated because it has a user-provided copy assignment operator
• Fix various issues with segmented_vector:
  • Fix copy/move construction/assignment so it doesn't do a shallow copy.
  • clear() now behaves like other eastl containers in that it does not free memory when called, the container maintains it's capacity.
  • segmented_vector now supports types which are not default constructible.
  • Added some missing API functions: reserve, resize, shrink_to_fit, emplace_back.
  • Added comparison operations.
• Add constructor overloads to map, set, hash_set, hash_map that take an initializer_list and Allocator.
• Enable some container asserts (when EASTL_ASSERT_ENABLED is enabled), removing the requirement for EASTL_EMPTY_REFERENCE_ASSERT_ENABLED. When called with invalid arguments these functions will result in undefined behaviour.
• Add some additional asserts to container adaptors.
• Fix undefined behaviour in shell_sort() algorithm.
• Add return values for deque, list, slists's member functions emplace_front(), emplace_back() and unique().
• Add slist::unique() function.
• Deprecate make_pair_ref(), use make_pair() instead. Also deprecate a make_pair() overload which was only enabled on MSVC.
• Deprecate stack::emplace_back(), use stack::emplace() instead.
• Fix references to std library that should be eastl.
• Fix compilation issues when C4626 is enabled as error on MSVC.
• Deprecate vector_map<Key, T>::at(index). this function was accidentally inherited from vector with incorrect semantics.
• Optimize bitset's find_first(), find_next(), find_last(), find_prev() (which are extensions to the standard).
• Fix bitset<N, eastl_uint128_t>::find_last().
• Added erase_unordered and erase_unordered_if for vector and deque (fixed_vector works implicitly with the
  vector version since it is a vector with a special allocator and these functions don't affect capacity). These
  work similar to free function erase/erase_if but are more efficient if those would result in moving a lot of
  elements. They achieve this by not respecting the order of the remaining element and just moving the elements from
  the end into the now empty spots.
• optional::emplace now correctly returns T& instead of void as specified in the standard.
• Explicitly define special member functions for some types. This fixes new compile errors from Visual Studio 17.7.0 Preview.
• Deprecate uninitialized_copy_ptr et al - uninitialized_copy is already perfectly suitable for pointers.
• Deprecate unwrap_iterator, is_reverse_iterator, is_move_iterator, is_insert_iterator, generic_iterator (the last is internal and should already be unused).
• Fix function::target not compiling due to missing template parameter when we called into the base class' member function.

Can this be git tag'd with the new version number, please, so we can request new package updates on vcpkg/conan?

Also, there's an outstanding issue to sha sign releases that might be nice to tackle: #506

@jhopkins-ea 👋 say hi to the team for me 😁

Could you also make a release tag in EABase https://github.com/electronicarts/EABase so this package can rely on correct version of EABase?
