Why use it
It provides direct, allocation-conscious access to compiled Blueprint execution and object interaction. No exception-based error path is implied by the signature.

Function
Performs `sub` as part of compiled Blueprint execution and object interaction.
Declaration 1 of 2
Declaration
inline Fixed sub(Fixed a, Fixed b)Performs `sub` as part of compiled Blueprint execution and object interaction.
| Parameter | Type | Meaning |
|---|---|---|
a | Fixed | Value supplied for a. Keep referenced or pointed-to data valid for the complete call. |
b | Fixed | Value supplied for b. Keep referenced or pointed-to data valid for the complete call. |
Returns: Fixed. Check the value before continuing when it represents success, availability or a resource handle.
Example
C++ example
#include "blueprint_runtime.hpp"
// Assume these named values have been initialized with valid data:
// Fixed a
// Fixed b
auto result = epok::bp::sub(a, b);Trade-offs and warnings
This is classified as **Engine internal**. Prefer a higher-level Epok service unless you need this exact control.

templateDeclaration
template<size_t Size> inline Vector<Size> sub(const Vector<Size>& a, const Vector<Size>& b)Performs `sub` as part of compiled Blueprint execution and object interaction.
| Parameter | Type | Meaning |
|---|---|---|
a | const Vector<Size> & | Value supplied for a. Keep referenced or pointed-to data valid for the complete call. |
b | const Vector<Size> & | Value supplied for b. Keep referenced or pointed-to data valid for the complete call. |
Returns: Vector<Size>. Check the value before continuing when it represents success, availability or a resource handle.
Example
C++ example
#include "blueprint_runtime.hpp"
// Replace these template arguments with types or values accepted by the declaration:
// Size
// Assume these named values have been initialized with valid data:
// const Vector<Size> & a
// const Vector<Size> & b
epok::bp& object = /* obtain a valid instance */;
auto result = object.sub<Size>(a, b);Why use it
Template dispatch is resolved at compile time and normally adds no runtime indirection.
Trade-offs and warnings
Every instantiated type must satisfy the header's compile-time requirements; extra instantiations can increase code size. This is classified as **Engine internal**. Prefer a higher-level Epok service unless you need this exact control. Pointer/reference arguments are borrowed unless the source contract says otherwise; keep them valid for the complete operation and never assume null is accepted.
