Expand description

Calculates the merkle root of an iterator of hashes.

Returns

  • None if hashes is empty. The merkle root of an empty tree of hashes is undefined.
  • Some(hash) if hashes contains one element. A single hash is by definition the merkle root.
  • Some(merkle_root) if length of hashes is greater than one.
