count: usize

strategy: IterationStrategy

Implementations

impl FilterPredicate

pub fn filter(&self, values: &dyn Array) -> Result<ArrayRef, ArrowError>

Selects rows from values based on this FilterPredicate

pub fn filter_record_batch( &self, record_batch: &RecordBatch, ) -> Result<RecordBatch, ArrowError>

Returns a filtered [RecordBatch] containing only the rows that are selected by this FilterPredicate.

This is the equivalent of calling filter on each column of the [RecordBatch].

pub fn count(&self) -> usize

Number of rows being selected based on this FilterPredicate
