Struct BlockReader 

pub struct BlockReader<'a> { /* private fields */ }

Reader for block data from Arrow batches.

Provides efficient access to block fields without copying data from the underlying Arrow columnar format. Each reader is bound to a specific row in the batch.

Implementations

impl<'a> BlockReader<'a>

pub fn new(batch: &'a RecordBatch, row_idx: usize) -> Result<Self>
