Struct SparseManifest 

pub struct SparseManifest {
    pub tree_hash: Hash,
    pub bitmap_root: Hash,
    pub filter_hash: Hash,
    pub leaf_count: u64,
}

Manifest committing to which tree entries the server is including in a sparse delivery. See SPEC-SPARSE-CHECKOUT §2.

All three fields are 32-byte BLAKE3 / SHA-256 digests. They are length-prefixed and content-addressed independently so a downstream codec can serialise them in any order.

Fields

tree_hash: Hash

BLAKE3 hash of the full tree object the manifest is derived from. Lets the client correlate this manifest with the tree_hash it asked the server for.

bitmap_root: Hash

Root of the MerkleizedBitMap over the include / exclude bitmap. SHA-256 (32 bytes) under the upstream mmr::Family hasher. Verifier MUST recompute this from the delivered bitmap chunks and reject on mismatch.

filter_hash: Hash

BLAKE3 hash of the canonicalised filter — see hash_filter. Binds the manifest to a specific filter so the server can’t substitute a different one mid-transfer.

leaf_count: u64

Total number of leaves in the source tree (= bitmap length in bits). Bounded by MAX_LEAVES.

Trait Implementations

impl Clone for SparseManifest

fn clone(&self) -> SparseManifest

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for SparseManifest

impl Debug for SparseManifest

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for SparseManifest

impl Hash for SparseManifest

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SparseManifest

fn eq(&self, other: &SparseManifest) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
