mp_units::constrained

A transparent wrapper that carries an error policy for domain constraint enforcement.

Synopsis

Declared in <mp-units/constrained.h>

template<
    typename T,
    typename ErrorPolicy = throw_policy>
class constrained;

Description

This wrapper does not check anything itself. It serves as a signal to the mp-units library that domain constraint violations should be reported via the ErrorPolicy rather than through precondition checks.

All arithmetic operations are forwarded to the underlying type T.
