Struct MerkleSignature 

pub struct MerkleSignature {
    pub root: [u8; 32],
    pub chunk_size: u64,
    pub file_size: u64,
    pub leaf_hashes: Vec<[u8; 32]>,
    pub chunk_entropies: Option<Vec<f32>>,
    pub chunk_simhashes: Option<Vec<u64>>,
}

Serializable Merkle signature for xattr/sidecar storage.

Fields

root: [u8; 32]

BLAKE3 root hash of the Merkle tree

chunk_size: u64

Chunk size used when building the tree

file_size: u64

File size at signature creation time

leaf_hashes: Vec<[u8; 32]>

Ordered leaf hashes (one per chunk)

chunk_entropies: Option<Vec<f32>>

Per-chunk Shannon entropy (bits/byte, 0.0-8.0). Present when any leaf has non-zero entropy.

chunk_simhashes: Option<Vec<u64>>

Per-chunk SimHash fingerprints. Present when similarity feature computed the hashes.
