Customization point for handling domain constraint violations.
Synopsis
Declared in <mp‐units/framework/customization_points.h>
template<typename Rep>
struct constraint_violation_handler;Description
The library calls constraint_violation_handler<Rep>::on_violation(msg) when a domain constraint is violated (e.g., out‐of‐bounds value, non‐negativity).
No default implementation is provided. When no specialization exists for a given Rep, the library uses MP_UNITS_EXPECTS directly (which may compile to nothing in release builds). Specializing this trait opts the type into guaranteed enforcement.
