Struct BatchSteps 

pub struct BatchSteps {
    pub dropped: u64,
    pub exact: bool,
    /* private fields */
}

A chain of inline steps compiled for one input schema.

Fields

dropped: u64

Rows dropped as poison (the per-row isolation path) since construction.

exact: bool

Whether every expression in the chain translated exactly (no per-row UDF fallback).

Implementations

impl BatchSteps

pub fn new(steps: Vec<Step>) -> Self

pub fn is_empty(&self) -> bool

pub fn apply( &mut self, batch: &RecordBatch, ) -> Result<RecordBatch, NotCompilable>

Apply the chain to a batch. Err(NotCompilable) means this schema cannot be handled on the batch path at all (fall back to rows); poison rows are isolated and counted, never an error.
