Struct arrow_select::filter::FilterBuilder

source ·
pub struct FilterBuilder { /* private fields */ }
Expand description

A builder to construct FilterPredicate

Implementations§

source§

impl FilterBuilder

source

pub fn new(filter: &BooleanArray) -> Self

Create a new FilterBuilder that can be used to construct a FilterPredicate

source

pub fn optimize(self) -> Self

Compute an optimised representation of the provided filter mask that can be applied to an array more quickly.

Note: There is limited benefit to calling this to then filter a single array Note: This will likely have a larger memory footprint than the original mask

source

pub fn build(self) -> FilterPredicate

Construct the final FilterPredicate
