zipPartialWith method
Combines the tuple of iterables to an iterable of tuples. The resulting
iterable has the length of the longest input iterable, missing values are
padded with padding
.
Implementation
Iterable<(T1, T2)> zipPartialWith((T1, T2) padding) sync* {
final i1 = $1.iterator, i2 = $2.iterator;
for (;;) {
final h1 = i1.moveNext(), v1 = h1 ? i1.current : padding.$1;
final h2 = i2.moveNext(), v2 = h2 ? i2.current : padding.$2;
if (h1 || h2) {
yield (v1, v2);
} else {
return;
}
}
}
