Struct cfx_internal_common::state_root_with_aux_info::StateRootAuxInfo

pub struct StateRootAuxInfo {
    pub snapshot_epoch_id: EpochId,
    pub intermediate_epoch_id: EpochId,
    pub maybe_intermediate_mpt_key_padding: Option<DeltaMptKeyPadding>,
    pub delta_mpt_key_padding: DeltaMptKeyPadding,
    pub state_root_hash: MerkleHash,
}

Auxiliary information for deferred state root, which is necessary for state trees look-up. The StateRootAuxInfo should be provided by consensus layer for state storage access.

Fields

snapshot_epoch_id: EpochId

intermediate_epoch_id: EpochId

maybe_intermediate_mpt_key_padding: Option<DeltaMptKeyPadding>

delta_mpt_key_padding: DeltaMptKeyPadding

state_root_hash: MerkleHash

Implementations

impl StateRootAuxInfo

pub fn genesis_state_root_aux_info(genesis_state_root: &MerkleHash) -> Self

Trait Implementations

impl Clone for StateRootAuxInfo

fn clone(&self) -> StateRootAuxInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StateRootAuxInfo

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

Formats the value using the given formatter.

impl Decodable for StateRootAuxInfo

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

Decode a value from RLP bytes

impl<'de> Deserialize<'de> for StateRootAuxInfo

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encodable for StateRootAuxInfo

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 StateRootAuxInfo

fn eq(&self, other: &StateRootAuxInfo) -> 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 StateRootAuxInfo

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 StateRootAuxInfo
