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.
