StrideIterator

Iterates an iterator with a fixed strides.

StrideIterator is used by stride.

struct StrideIterator(Iterator)
@optmath
struct StrideIterator (
Iterator
) {
@optmath
ptrdiff_t _stride;
@optmath
Iterator _iterator;
auto lightConst();
auto lightImmutable();
alias __map(alias fun) = StrideIterator__map!(Iterator, fun);
auto ref opUnary();
void opUnary();
auto ref opIndex(ptrdiff_t index);
void opOpAssign(ptrdiff_t index);
auto opBinary(ptrdiff_t index);
ptrdiff_t opBinary(typeof(this) right);
bool opEquals(typeof(this) right);
ptrdiff_t opCmp(typeof(this) right);
}
