Module iter 

Summary: Iterator configuration and scan metrics for Phase 2 read dominance. Copyright (c) YOAB. All rights reserved.

This module provides:

• IterOptions: Configuration for iterator behavior (prefetch hints, etc.)
• ScanMetrics: Statistics collected during iteration
• MetricsIter: Iterator wrapper that collects scan metrics

Performance Considerations

• Prefetch hints allow the iterator to load upcoming data proactively.
• Metrics collection has minimal overhead when enabled.
• All structures are designed for cache-friendly access patterns.

Structs

IterOptions

Configuration options for iterators.

MetricsIter

An iterator wrapper that collects scan metrics.

PrefetchIter

Iterator with prefetch hints for optimized sequential access.

ScanMetrics

Metrics collected during a scan operation.
