partial¶
Header¶
#include <fit/partial.hpp>
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 repeatedly do this until the function can
finally be called. By default, partial
captures all of its 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);
Semantics¶
assert(partial(f)(xs...)(ys...) == f(xs..., ys...));
Example¶
#include <fit.hpp>
#include <cassert>
using namespace fit;
struct sum
{
template<class T, class U>
T operator()(T x, U y) const
{
return x+y;
}
};
int main() {
assert(3 == partial(sum())(1)(2));
}
