Function calculate_root

pub fn calculate_root<T, I>(hashes: I) -> Option<T>where
    T: Hash + Encodable,
    <T as Hash>::Engine: Write,
    I: Iterator<Item = T>,

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.
