stride

fnauto stride(Range)(Range r, size_t n) if (isInputRange!(Unqual!Range))

Iterates range r with stride n. If the range is a random-access range, moves by indexing into the range; otherwise, moves by successive calls to popFront. Applying stride twice to the same range results in a stride with a step that is the product of the two applications. It is an error for n to be 0.

Parameters

rthe input range to stride over
nthe number of elements to skip over

Returns

At minimum, an input range. The resulting range will adopt the

range primitives of the underlying range as long as hasLength is true.
