Struct casper_hashing::Digest[−][src]

Hashes a Vec of Digests into a single Digest by constructing a Merkle tree. Reduces pairs of elements in the Vec by repeatedly calling Digest::hash_pair. This hash procedure is suited to hashing BTrees.

The pattern of hashing is as follows. It is akin to graph reduction:

a b c d e f
|/  |/  |/
g   h   i
| /   /
|/   /
j   k
| /
|/
l

Returns Digest::SENTINEL_MERKLE_TREE when the input is empty.

[src]

pub fn hash_btree_map<K, V>(btree_map: &BTreeMap<K, V>) -> Result<Digest, Error> where
K: ToBytes,
V: ToBytes,

Hashes a BTreeMap.

[src]

pub fn hash_slice_rfold(slice: &[Digest ]) -> Digest

Hashes a &[Digest] using a right fold.

This pattern of hashing is as follows:

hash_pair(a, &hash_pair(b, &hash_pair(c, &SENTINEL_RFOLD)))

Unlike Merkle trees, this is suited to hashing heterogeneous lists we may wish to extend in the future (ie, hashes of data structures that may undergo revision).

Returns Digest::SENTINEL_RFOLD when given an empty slice as input.

[src]

pub fn hash_slice_with_proof(slice: &[Digest ], proof: Digest) -> Digest

Hashes a &[Digest] using a right fold. Uses proof as a Merkle proof for the missing tail of the slice.
