bitpack

Bitpack slice over an integral slice.

Bitpack is used to represent unsigned integer slice with fewer number of bits in integer binary representation.

auto bitpack(Slice!(Iterator, N, kind) slice)
auto bitpack(T[] array)
auto bitpack(T withAsSlice)
@optmath
auto
bitpack
(
size_t pack
T
)
(
T withAsSlice
)
if (
hasAsSlice!T
)

Parameters

pack: counts of bits in the integer.

Return Value

Type: auto

A bitpack slice.

Examples

size_t[10] data;
// creates a packed unsigned integer slice with max allowed value equal to `2^^6 - 1 == 63`.
auto packs = data[].bitpack!6;
assert(packs.length == data.length * size_t.sizeof * 8 / 6);
packs[$ - 1] = 24;
assert(packs[$ - 1] == 24);

packs.popFront;
assert(packs[$ - 1] == 24);
