stride

Strides 1-dimensional slice.

auto stride(Slice!(Iterator, N, kind) slice, ptrdiff_t factor)

stride
(
Iterator
size_t N
SliceKind kind
)
(
Slice!(Iterator, N, kind) slice
,
ptrdiff_t factor
)
if (
N == 1
)
template stride(size_t factor = 2)
auto stride(T[] array, ptrdiff_t factor)
auto stride(T withAsSlice, ptrdiff_t factor)

Parameters

slice Slice!(Iterator, N, kind): 1-dimensional unpacked slice.
factor ptrdiff_t: positive stride size.

Return Value

Type: auto

Contiguous slice with strided iterator.

Examples

auto slice = iota(6);
static immutable str = [0, 2, 4];
assert(slice.stride(2) == str); // runtime factor
assert(slice.stride!2 == str); // compile time factor
assert(slice.stride == str); // default compile time factor is 2
assert(slice.universal.stride(2) == str);

ND-compile time

auto slice = iota(4, 6);
static immutable str = [[0, 2, 4], [12, 14, 16]];
assert(slice.stride!2 == str); // compile time factor
assert(slice.stride == str); // default compile time factor is 2
