EnTT Files

Changelog

• core
• Skip most of vtable calls in any for references and dynamically allocated objects
• Review any_policy values to better capture the nature of the elements stored with any
• Added any::owner() because any_policy::owner is no longer available
• Embedded-as-dynamic support for any (useful to transfer ownership of externally allocated objects)
• is_iterator and is_equality_comparable review to refine them further
• Self-moving an any puts it in a safe but unspecified state now
• Introduce ENTT_CONSTEVAL config parameter

• Apply consteval on appropriate hashed string related functions

• entity:

• deletion_policy::unspecified is now available and equal to swap_and_pop
• Skip tombstone checks in more cases and improve performance of view iterators
• Auto-disconnection support for reactive_mixin
• Refined storage fallback mechanism for views to make it work across boundaries
• Support joining views with storage objects directly
• Introduce generate functions in the storage entity to replace emplace
• Add generate functions to the sigh mixin to fully support storage entity
• as_view and as_group are now copyable
• Improved shrink_to_fit to also cleanup the sparse array of a sparse set
• Extended basic_registry<...>::storage<T> const-correctness
• Allow customizing component_traits based on the entity type
• Default group template parameters for Get and Exclude lists
• Make basic_organizer support groups too
• Fix a bug on view packs when combining views with uninitialized filters
• Make built-in storage mixins support custom private/protected registries
• Support to reserved entities (see start_from on the entity storage)

• Make to_entity work properly with stable types

• meta:

• meta_sequence_container::rebind is no longer available
• meta_associative_container::rebind is no longer available
• meta_any::base() to return a const reference to the underlying any
• Deprecated meta_any_policy, meta_any::policy() and meta_any::data()
• Self-contained meta_factory<T> to avoid having to go through meta<T>
• Support taking ownership of passed in pointers on construction for meta_any
• meta_type::from_void allows transferring ownership of elements too
• Standalone meta_data and meta_func implementations
• Make empty meta_data, meta_func and meta_type safe to use no matter what
• Self-moving a meta_any puts it in a safe bug unspecified state now
• Allow attaching const values of non-Type type to meta types
• Make as_ref return valid objects when the underlying type is void
• meta_any::context() returns the underling meta context
• Deprecated multi-setters meta data support
• Deprecated context-aware meta_getter utilities
• Get the context from the instance in the remaining meta_getter utilities
• Deprecated context-aware meta_invoke utilities
• Get the context from the instance in the remaining meta_invoke utilities
• Support deducing meta pointers like types directly

• Early exit for typed allow_cast

• signal:

• Make it possible to create uninitialized sink objects
• Updated definition for emitter::publish (no forwarding references)
• Slightly review sink API (these changes should be backward compatible)

Build system

• Updated IWYU version
• Updated lcov configuration to make gtest work with lcov2
• ENTT_INSTALL to enable/disable installation steps as needed

Any other business

• Removed all previously deprecated methods

Natvis support

All natvis files have been updated where necessary.

Breaking changes

• core:

• Reviewed any_policy values with breaking changes in names to avoid subtle errors on user side

• entity:

• Deprecated emplace in the storage entity, use generate instead

• component_traits accepts entity types (possibly breaking if specialized when using a custom entity type), refine specializations

• meta:

• meta_sequence_container::rebind was removed, use the constructor instead
• meta_associative_container::rebind was removed, use the constructor instead
• Deprecated meta_any_policy, use any_policy instead
• Deprecated meta_any::policy(), use .base().policy() instead
• Deprecated meta_any::data(), use .base().data()
• Deprecated meta<T>, use meta_factory<T> directly instead
• Deprecated multi-setters meta data support, use variant or convertible types instead
• Deprecated context-aware meta_getter utilities, rebind the handle as needed instead
• Deprecated context-aware meta_invoke utilities, rebind the handle as needed instead

Any other business

The documentation is up-to-date and the library is battle-tested with 100% coverage as usual. I started a long term process to reduce the number of instantiations and also speed up the compilation. This release contains some changes in this regard. Still a work in progress though.
