Typedefs

DirtyComponentSpec

template <template< typename, typename... > typename TComponent, typename... TArgs>

using helios::engine::core::types::DirtyComponentSpec = typedef ComponentTypeSpec<TComponent, TArgs...>

Functions

fnv1a_hash()

constexpr uint32_t helios::engine::core::types::fnv1a_hash (const std::string_view str)

constexpr noexcept

Computes a 32-bit FNV-1a hash from a string.

Implements the Fowler–Noll–Vo hash function (FNV-1a variant), a fast, non-cryptographic hash suitable for hash tables and identifier generation. The function is constexpr, enabling compile-time hashing of string literals.

Definition at line 49 of file FuncDefs.ixx.

49 [[nodiscard]] constexpr uint32_t fnv1a_hash(const std::string_view str) noexcept {

50 uint32_t hash = 2166136261U;

51 for (char c: str) {

52 hash ^= static_cast<uint8_t>(c);

53 hash *= 16777619U;

54 }

55 return hash;

56 }

Variables

no_init

constexpr no_init_t helios::engine::core::types::no_init

constexpr

Tag constant for requesting uninitialized construction.

This is a convenience instance of no_init_t that can be passed to constructors supporting uninitialized construction.
