Struct IndexReader 

pub struct IndexReader { /* private fields */ }

High-level Index.db file reader

Implementations

impl IndexReader

pub async fn open(path: &Path, platform: Arc<Platform>) -> Result<Self>

Open and parse an Index.db file

pub async fn open_with_summary( path: &Path, platform: Arc<Platform>, summary_reader: Option<&SummaryReader>, ) -> Result<Self>

Open and parse an Index.db file with Summary.db correlation for proper offset mapping

pub fn get_partition_entries(&self) -> &[PartitionIndexEntry]

Get all partition entries

pub fn lookup_partition( &self, key_digest: &[u8], ) -> Option<&PartitionIndexEntry>

Look up a partition by key digest

Zero-Allocation Optimization (Issue #107)

This method performs HashMap lookup without heap allocation by leveraging the Borrow trait. Since Arc<[u8]> implements Borrow<[u8]>, we can lookup using &[u8] directly without creating a temporary Arc.

Before: let key_arc: Arc<[u8]> = key_digest.into(); (heap allocation per query) After: Direct get(key_digest) using Borrow trait (zero allocations)

pub fn get_statistics(&self) -> IndexStatistics

Get statistics about the index

pub async fn validate_integrity(&self) -> Result<Vec<String>>

Validate index integrity against Data.db offsets
