Struct ScanIterator 

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

Iterator that reads rows from table storage.

This is the leaf node in the iterator tree, providing rows from the underlying storage layer.

Note: Currently unused due to lifetime constraints with SqlTransaction. Reserved for future true streaming execution when those constraints are resolved. The current implementation uses VecIterator after collecting all rows from scan.

Implementations

impl<'a> ScanIterator<'a>

pub fn new(inner: TableScanIterator<'a>, table_meta: &TableMetadata) -> Self

Creates a new scan iterator from a table scan iterator and metadata.

Trait Implementations

impl RowIterator for ScanIterator<'_>

fn next_row(&mut self) -> Option<Result<Row>>

Advances the iterator and returns the next row, or None if exhausted.

fn schema(&self) -> &[ColumnMetadata]

Returns the schema of rows produced by this iterator.
