Description

Operator struct template to check if an expression throws a specific exception.

Template Parameters

Callable_T	The type of the callable object to be invoked.
Exception_T	The type of the exception to check for (defaults to void for any exception).

The throws_ struct template provides a type-safe mechanism for verifying whether a callable expression throws a specified exception type 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.

Public Constructors

throws_()

template <class Callable_T, class Exception_T = void>

micro_os_plus::micro_test_plus::detail::throws_< Callable_T, Exception_T >::throws_ (const Callable_T & func)

inline explicit constexpr

Constructs an exception checking operator for the given callable.

Parameters

func	The callable object to be invoked.

Invokes the provided callable and determines whether it throws an exception of the specified type. The result is stored in the value_ member for efficient access.

Public Operators

operator bool()

micro_os_plus::micro_test_plus::detail::throws_< Callable_T, Exception_T >::operator bool ()

inline nodiscard constexpr

Conversion operator to boolean.

Parameters

None.

Return Values

true	The callable throws the specified exception type.
false	The callable does not throw the specified exception type.

Returns the result of the exception check.
