Struct ScanCursor 

pub struct ScanCursor<'view> { /* private fields */ }

Forward cursor tied to one protected view. No full candidate collection. v2 (B7 follow-up): when the view’s current-value fast path is valid (see ReadView::native_range), one real backend cursor serves the whole scan — built lazily on the first Self::next_batch call and held across calls (native/native_checked). Otherwise falls back to v1’s ordered seek-per-row (next_key + read_value_with_limits). Each batch plus at most one bounded lookahead row is allocated. Callers must release consumed batches; shared outstanding-byte admission is P01.

Implementations

impl ScanCursor<'_>

pub fn next_batch( &mut self, row_limit: usize, byte_limit: usize, ) -> Result<ScanBatch, StorageError>

Fetch up to row_limit rows bounded by byte_limit copied bytes.

Errors

Returns StorageError::InvalidRead for zero limits, StorageError::Cancelled if the view was cancelled, or StorageError::ResourceExhausted if a single row exceeds byte_limit.
