Public Member Functions
constexpr	nothrow_ (const Callable_T &func)
	Constructs a nothrow checking operator for the given callable.
constexpr	operator bool () const
	Conversion operator to boolean.

Public Attributes
const bool	value_ {}
	Stores the result of the nothrow check.

Detailed Description

template<class Callable_T>
struct micro_os_plus::micro_test_plus::detail::nothrow_< Callable_T >

Template Parameters

Callable_T

The type of the callable object to be invoked.

The nothrow_ struct template provides a type-safe mechanism for verifying whether a callable expression completes without throwing any exception during its execution within the framework.

This comparator is designed to support both custom and standard callable types. The result of the exception check is stored in the value_ member for efficient access.

The implementation is optimised for use in embedded environments and supports both compile-time and run-time evaluation.

All definitions are intended for internal use within the framework and are implemented in the include/micro-os-plus/micro-test-plus folder to maintain a structured and modular codebase.

Parameters

func	The callable object to be invoked.
