partial

Description

The partial function adaptor allows partial application of the function. If the function can not be called with all the parameters, it will return another function. It will continually do this until the function can finally be called. By default, partial captures all of it variables by value, just like bind. std::ref can be used to capture references instead.

Synopsis

template<class F>
constexpr partial_adaptor<F> partial(F f);

Requirements

F must be:

FunctionObject
MoveConstructible

Example

struct sum
{
    template<class T, class U>
    T operator()(T x, U y) const
    {
        return x+y;
    }
};

assert(3 == partial(sum())(1)(2));
