Wraps a function taking N arguments into a function which accepts a tuple of N arguments. Note: This function will also accept an std::pair if N == 2.
Synopsis
Declared in <folly/functional/ApplyTuple.h>
template<class F>
/* implementation-defined */
uncurry(F&& f);Description
For example, given the below code:
std::vector<std::tuple<int, int, int>> rows = ...; auto test = []int, int>& row) { return std::get<0>(row) * std::get<1>(row) * std::get<2>(row) == 24; }; auto found = std::find_if(rows.begin(), rows.end(), test);
'test' could be rewritten as:
auto test = folly::uncurry([]a, int b, int c) { return a * b * c == 24; });
Return Value
