#8505 closed Feature Requests (fixed)

Add a C++11 conforming move semantics to function<> class

Reported by: viboes Owned by: Antony Polukhin
Milestone: To Be Determined Component: function
Version: Boost 1.54.0 Severity: Problem
Keywords: Cc: antoshkka@…

Description

C++11 std::function provides move semantics. It would be great if Boost.Function could provide it on C++11 compilers and use Boost.Move on C++ compilers that don't provide rvalue references. 

function(function&&);
function& operator=(function&&);
template<class F> function& operator=(F&&);

This issue has been fixed in #7330 without usage of Boost.Move.

Discussion about adding Boost.Move to old libraries can be found ​here. In short: adding Boost.Move to existing libraries breaks user code.

template<class F> function& operator=(F&&); does not conform C++ Standard and may intentionally break users code on some compilers.

Only one thing remains undone: update documentation.
