Crysda::NullBitmap

=========================================================================== Null Bitmap - 1 bit per element for efficient null tracking Uses UInt64 words with SIMD acceleration for bulk operations

SIMD_THRESHOLD = 4

SIMD threshold - use SIMD for bitmaps with >= this many words

build(size : Int32, &) : NullBitmap

Build bitmap directly from parsing - avoids intermediate Array(T?)

from_nullable(arr : Array) : NullBitmap

new(size : Int32)

none(size : Int32) : NullBitmap

&(other : NullBitmap) : NullBitmap

Optimized AND - uses SIMD for large bitmaps

[](index : Int32) : Bool

|(other : NullBitmap) : NullBitmap

Optimized OR - uses SIMD for large bitmaps

any?

clear(index : Int32) : Nil

count

Optimized count using SIMD popcount where available

none?

set(index : Int32) : Nil

size
