Function Documentation

template<typename It >

outcome::result<common::Buffer> kagome::storage::trie::calculateOrderedTrieHash	(	const It &	begin,
		const It &	end
	)

Calculates the hash of a Merkle tree containing the items from the provided range [begin; end) as values and compact-encoded indices of those values(starting from 0) as keys

Template Parameters

It	an iterator type of a container of common::Buffers

Returns

the Merkle tree root hash of the tree containing provided values
