std::function_ref

Member functions

function_ref::function_ref

function_ref::operator=

function_ref::operator()

Deduction guides

 

R operator()( Args... args ) const noexcept(/*noex*/);		(since C++26)

Invokes the stored thunk-ptr with bound-entity as its first parameter and the rest of the parameters args. The /*noex*/ part of operator() is identical to those of the template parameter of std::function_ref.

Equivalent to return thunk-ptr(bound-entity, std::forward<Args>(args)...);.

Parameters

args

-

rest parameters to pass to the stored thunk-ptr

Return value

thunk-ptr(bound-entity, std::forward<Args>(args)...).

Exceptions

Propagates the exception thrown by the underlying function call.

operator()	calls the stored function (public member function of std::reference_wrapper<T>)
