Types Documentation¶

enum TrieError¶

Enumerator	Value	Description
NO_VALUE	1

TrieDbError enum provides error codes for TrieDb methods.

Functions Documentation¶

function calculateOrderedTrieHash¶

template <typename It >
outcome::result< base::Buffer > calculateOrderedTrieHash(
    const It & begin,
    const It & end
)

Template Parameters:

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

Return: the Merkle tree root hash of the tree containing provided values

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

function byteFromNibbles¶

inline uint8_t byteFromNibbles(
    uint8_t high,
    uint8_t low
)

function ushortToBytes¶

inline base::Buffer ushortToBytes(
    uint16_t b
)

Attributes Documentation¶

variable EXTRINSIC_INDEX_KEY¶

const base::Buffer EXTRINSIC_INDEX_KEY                                    =
base::Buffer{}.put(":extrinsic_index");

variable NO_EXTRINSIC_INDEX_VALUE¶

const base::Buffer NO_EXTRINSIC_INDEX_VALUE {
      scale::encode(0xffffffff).value()};
