    // Required method
    fn apply_transformation(
        &self,
        record_batch: RecordBatch,
    ) -> Option<RecordBatch>;
}

A trait for nodes that can apply transformations to a RecordBatch.

Required Methods

fn apply_transformation(&self, record_batch: RecordBatch) -> Option<RecordBatch>

Apply the transformation to the RecordBatch and return the result.

Trait Implementations

impl PartialEq<&Box<dyn RecordBatchExpr>> for Box<dyn RecordBatchExpr>

fn eq(&self, other: &&Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq for Box<dyn RecordBatchExpr>

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
