Struct BooleanColumn 

pub struct BooleanColumn { /* private fields */ }

A column of true/false values (pond-ts kind: 'boolean'). A gap is an Arrow null. Held as an Arrow Boolean array (one bit per row).

Implementations

impl BooleanColumn

pub fn from_options(values: impl IntoIterator<Item = Option<bool>>) -> Self

Build from optional values; None is a gap.

pub fn len(&self) -> usize

Number of values.

pub fn is_empty(&self) -> bool

true when there are no values.

pub fn get(&self, i: usize) -> Option<bool>

The value at i, or None for a gap. Panics if i is out of range.

pub fn iter(&self) -> impl Iterator<Item = Option<bool>> + '_

Iterate as Option<bool>.

pub fn missing_count(&self) -> usize

Number of gaps.
