Typed column vector for SIMD-friendly access

Each variant stores contiguous values for vectorized operations.

Variants

Bool(Vec<bool>)

Boolean column (bit-packed for SIMD)

Int64(Vec<i64>)

64-bit signed integers (SIMD-friendly)

UInt64(Vec<u64>)

64-bit unsigned integers

Float64(Vec<f64>)

64-bit floats

String

Variable-length strings (Arrow-style: offsets + data)

Fields

offsets: Vec<u32>

data: Vec<u8>

Binary

Binary data (Arrow-style: offsets + data)

Fields

offsets: Vec<u32>

data: Vec<u8>

Null(Vec<u64>)

Null bitmap for any column (packed bits)
