Struct MmapBlockIndex 

pub struct MmapBlockIndex { /* private fields */ }

Mmap’d raw block index (Option 2)

Keeps the prefix-compressed block index as raw bytes and decodes entries on-demand. No heap allocation for keys.

Implementations

impl MmapBlockIndex

pub fn build(entries: &[(Vec<u8>, BlockAddr)]) -> Result<Vec<u8>>

Build mmap-friendly index from entries

pub fn load(data: OwnedBytes) -> Result<Self>

Load from raw bytes

pub fn locate(&self, target: &[u8]) -> Option<usize>

Binary search for a key, returning the block ordinal Decodes keys on-demand during the search

pub fn get_addr(&self, ordinal: usize) -> Option<BlockAddr>

Get block address by ordinal

pub fn len(&self) -> usize

Number of blocks

pub fn is_empty(&self) -> bool

Check if empty

pub fn all_addrs(&self) -> Vec<BlockAddr>

Get all block addresses

pub fn all_keys(&self) -> Vec<Vec<u8>>

Decode all keys (for debugging/merging)
