Struct TransposedBool 

pub struct TransposedBool;

The array encoding for a boolean bitmap stored in FastLanes-transposed order.

Implementations

impl TransposedBool

pub fn try_new(transposed: ArrayRef) -> VortexResult<TransposedBoolArray>

Creates an array from a boolean array already stored in FastLanes-transposed order.

The transposed array may use any encoding (e.g. a lazy slice); it is canonicalized when this array is executed.

Errors

Returns an error if transposed is not a non-nullable boolean array containing complete 1,024-bit chunks.

Trait Implementations
