BitField

mir ndslice field

BitField is used by bitwise.

@optmath
struct BitField (
Field
I = typeof(cast()Field.init[size_t.init])
) if (
__traits(isUnsigned, I)
) {
import mir.bitop : ctlz;;
alias E = I;
package
@optmath
enum shift;
@optmath
Field _field;
auto __vmap(Fun fun);
auto __vmap(Fun fun);
auto __vmap(Fun fun);
alias __map(alias fun) = BitField__map!(Field, I, fun);
auto lightConst();
auto lightImmutable();
bool opIndex(size_t index);
bool opIndexAssign(bool value, size_t index);
static if(hasZeroShiftFieldMember!Field)
auto assumeFieldsHaveZeroShift();
