inlinenoexcept |
Builds a function that targets a copy of the incoming function object.
__f | A function object that is callable with parameters of type ArgTypes... and returns a value convertible to Res. |
The newly-created function object will target a copy of __f. If __f is reference_wrapper<F>, then this function object will contain a reference to the function object __f.get(). If __f is a null function pointer, null pointer-to-member, or empty std::function, the newly-created object will be empty.
If __f is a non-null function pointer or an object of type reference_wrapper<F>, this function will not throw.

__f | A function object that is callable with parameters of type _ArgTypes... and returns a value convertible to _Res. |
This function object wrapper will target a copy of __f. If __f is reference_wrapper<F>, then this function object will contain a reference to the function object __f.get(). If __f is a null function pointer or null pointer-to-member, this object will be empty.
If __f is a non-null function pointer or an object of type reference_wrapper<F>, this function will not throw.

Function assignment operator.
__x | A function with identical call signature. |
The target of __x is copied to *this. If __x has no target, then *this will be empty.
If __x targets a function pointer or a reference to a function object, then this operation will not throw an exception.
