Typedef Documentation

StringHash32

using Cori::Utility::StringHash32 = entt::hashed_string::hash_type

Definition at line 19 of file StringHash.hpp.

StringHash64

using Cori::Utility::StringHash64 = uint64_t

Definition at line 18 of file StringHash.hpp.

Function Documentation

AABBOverlapCheck()

bool Cori::Utility::AABBOverlapCheck ( const AABB & a, const AABB & b )

inlinenodiscard

Checks if 2 AABBs overlap.

Parameters

a	First AABB.
b	Second AABB.

Returns

True if overlap, false othwerise.

Definition at line 47 of file AABB.hpp.

CalculateAABB()

AABB Cori::Utility::CalculateAABB ( const glm::mat3 & transform, const glm::vec2 halfSize )

inlinenodiscard

Calculates the AABB for the quad taking into account rotation and scale.

Parameters

transform	Transform of the quad. Position in the matrix should be the center of the quad.
halfSize	Half size of the quad.

Returns

A calculated AABB.

Definition at line 22 of file AABB.hpp.

fnv1a64()

std::uint64_t Cori::Utility::fnv1a64 ( const char * str, const std::size_t len )

constexpr

Computes the 64bit FNV-1a string hash.

Definition at line 9 of file StringHash.hpp.

GetAggregateStructUID()

template<typename T>

uint64_t Cori::Utility::GetAggregateStructUID ( )

consteval

Generates a stable, unique ID for an aggregate struct at compile-time.

Template Parameters

T	Struct type to generate the UID for.

Returns

Unique struct ID.

The ID is sensitive to the struct's name and the order and types of its members.
It is stable across different runs for the same compiler.

Definition at line 56 of file AggregateStructUID.hpp.

Here is the call graph for this function:

Utf8ToUtf32() [1/2]

std::u32string Cori::Utility::Utf8ToUtf32 ( const std::string & string )

inline

Converts a UTF-8 variable length encoded string to a UTF-32 fixed length encoded string.

Parameters

string

UTF-8 variable length encoded string.

Returns

UTF-32 fixed length encoded string.

Definition at line 37 of file UTF.hpp.

Here is the call graph for this function:

Utf8ToUtf32() [2/2]

std::u32string Cori::Utility::Utf8ToUtf32 ( const std::string_view & view )

inline

Converts a UTF-8 variable length encoded string to a UTF-32 fixed length encoded string.

Parameters

view	View to the UTF-8 variable length encoded string.

Returns

UTF-32 fixed length encoded string.

Definition at line 11 of file UTF.hpp.
