Struct IndexHeader 

pub struct IndexHeader { /* private fields */ }

The 1032-byte fanout/header of a previously authenticated v2 index. Parsing checks layout and fanout shape. It does NOT verify the full index checksum, ID ordering, or its relationship to pack contents. Establish those when importing/creating the index, before trusting lookup results or absence. The header and every range reply must refer to that same immutable snapshot.

Implementations

impl IndexHeader

pub const BYTES: usize = 1032

pub fn parse( format: ObjectFormat, header: &[u8], index_bytes: u64, pack_bytes: u64, ) -> Result<IndexHeader, Error>

pub fn object_count(&self) -> u32

pub fn lookup(&self, id: ObjectId) -> Result<IndexLookup, Error>

Start a fanout-limited binary search. The lookup owns only fixed state, so unrelated lookups can interleave storage operations without a lock.
