Struct BoolVector 

Source 
pub struct BoolVector { /* private fields */ }
Expand description

An immutable vector of boolean values.

Internally, this BoolVector is a wrapper around a BitBuffer and a validity mask.

Implementations§

Source§

impl BoolVector

Source

pub fn new(bits: BitBuffer, validity: Mask) -> Self

Creates a new BoolVector from the given bits and validity mask.

§Panics

Panics if the length of the validity mask does not match the length of the bits.

Source

pub fn try_new(bits: BitBuffer, validity: Mask) -> VortexResult<Self>

Tries to create a new BoolVector from the given bits and validity mask.

§Errors

Returns an error if the length of the validity mask does not match the length of the bits.

Source

pub unsafe fn new_unchecked(bits: BitBuffer, validity: Mask) -> Self

Creates a new BoolVector from the given bits and validity mask without validation.

§Safety

The caller must ensure that the validity mask has the same length as the bits.

Source

pub fn into_parts(self) -> (BitBuffer, Mask)

Decomposes the boolean vector into its constituent parts (bit buffer and validity).

Source

pub fn bits(&self) -> &BitBuffer

Returns the bits buffer of the boolean vector.
