Detailed Description

struct EntropyCanvas::Schema::TypeID;

A cross-platform type identifier with stable hashing and comparison.

Note: TypeID objects are immutable and safe to use across thread boundaries

TypeID provides a consistent way to identify types at runtime across different platforms and compilers. It uses boost::type_index internally to generate stable hash codes and human-readable type names.

Features:

• Stable hash codes across compilation units
• Human-readable type names with template parameters (optionally compiled in)
• Supports comparison operations
• Compatible with standard containers (via std::hash specialization)

Example usage:

auto intTypeId = createTypeId<int>();
auto floatTypeId = createTypeId<float>();

if (intTypeId == floatTypeId) {
    // Never executed - different types
}

Public Functions Documentation

function prettyName

inline std::string prettyName() const

Get the human-readable type name.

Return: The pretty-printed name of the type with template parameters

This method returns the same value as the [name](/api/EntropyEngine/Core/TypeSystem/TypeID/#variable-name) member but provides a method-based interface for consistency with other APIs.

function operator==

inline bool operator==(
    const TypeID & other
) const

Equality comparison operator.

Parameters:

• other The TypeID to compare against

Return: true if both TypeIDs represent the same type

function operator<=>

inline auto operator<=>(
    const TypeID & other
) const

Three-way comparison operator for ordering TypeIDs.

Parameters:

• other The TypeID to compare against

Return: std::strong_ordering result based on hash comparison

Public Attributes Documentation

variable name

std::string name;

Human-readable name of the type.

Contains the canonical type name including template parameters. For example: “glm::vec<3, float>” or “std::vector”.

variable id

uint64_t id;

64-bit canonical hash identifier for the type

Derived from boost::type_index::hash_code() and normalized to uint64_t for cross-ABI stability within a build.
