Struct primitives::state_root::StateRoot

pub struct StateRoot {
    pub snapshot_root: MerkleHash,
    pub intermediate_delta_root: MerkleHash,
    pub delta_root: MerkleHash,
}

The deferred state root consists of 3 parts: snapshot, delta_0, delta. when delta grows over threshold, snapshot and delta_0 is merged into new snapshot, and the delta becomes new delta_0.

Fields

snapshot_root: MerkleHash

intermediate_delta_root: MerkleHash

delta_root: MerkleHash

Implementations

impl StateRoot

pub fn compute_state_root_hash(&self) -> H256

pub fn genesis(genesis_root: &MerkleHash) -> StateRoot

Trait Implementations

impl Clone for StateRoot

fn clone(&self) -> StateRoot

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StateRoot

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Decodable for StateRoot

fn decode(rlp: &Rlp<'_>) -> Result<Self, DecoderError>

Decode a value from RLP bytes

impl Default for StateRoot

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for StateRoot

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encodable for StateRoot

fn rlp_append(&self, s: &mut RlpStream)

Append a value to the stream

fn rlp_bytes(&self) -> Vec<u8>

Get rlp-encoded bytes for this instance

impl PartialEq for StateRoot

fn eq(&self, other: &StateRoot) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for StateRoot

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for StateRoot

impl StructuralPartialEq for StateRoot
