Struct ColumnPtrs 

pub struct ColumnPtrs {
    pub values_ptr: *const u8,
    pub offsets_ptr: *const u8,
    pub validity_ptr: *const u8,
    pub stride: usize,
    pub data_type: DataType,
}

Raw pointers to Arrow column buffers for zero-cost field access.

These pointers are derived from the underlying Arrow arrays and remain valid as long as the parent DataTable (and its RecordBatch) is alive.

Fields

values_ptr: *const u8

Pointer to the values buffer (f64, i64, bool bytes, etc.)

offsets_ptr: *const u8

Pointer to the offsets buffer (for variable-length types like Utf8)

validity_ptr: *const u8

Pointer to the validity bitmap (null tracking)

stride: usize

Stride in bytes between consecutive values (0 for variable-length)

data_type: DataType

Arrow data type for this column
