Primitive tuple

Splits an array of pairs into a pair of arrays.

Both arrays produced have the same length as the input array. The first element of the left array is the first element of the first tuple, the second element the first element of the second tuple, and so on. In other words, the array [(l0, r0), (l1, r1), (l2, r2), ...] is split into [l0, l1, l2, ...] and [r0, r1, r2, ...].

Examples

let (l, r) = [(10u8, 20u8), (11u8, 21u8), (12u8, 22u8)].unzip();
assert l == [10u8, 11u8, 12u8];
assert r == [20u8, 21u8, 22u8];
let empty: [(uint<8>, uint<8>); 0] = [];
assert empty.unzip() == ([], []);
