Struct exonum::blockchain::Block

pub struct Block {
    pub proposer_id: ValidatorId,
    pub height: Height,
    pub tx_count: u32,
    pub prev_hash: Hash,
    pub tx_hash: Hash,
    pub state_hash: Hash,
}

Exonum block header data structure.

A block is essentially a list of transactions, which is a result of the consensus algorithm (thus authenticated by the supermajority of validators) and is applied atomically to the blockchain state.

The header only contains the amount of transactions and the transactions root hash as well as other information, but not the transactions themselves.

Fields

proposer_id: ValidatorId

Identifier of the leader node which has proposed the block.

height: Height

Height of the block, which is also the number of this particular block in the blockchain.

tx_count: u32

Number of transactions in this block.

prev_hash: Hash

Hash link to the previous block in the blockchain.

tx_hash: Hash

Root hash of the Merkle tree of transactions in this block.

state_hash: Hash

Hash of the blockchain state after applying transactions in the block.

Methods

impl Block

pub fn new(
    proposer_id: ValidatorId,
    height: Height,
    tx_count: u32,
    prev_hash: Hash,
    tx_hash: Hash,
    state_hash: Hash
) -> Self

Create new Block.

pub fn proposer_id(&self) -> ValidatorId

Identifier of the leader node which has proposed the block.

pub fn height(&self) -> Height

Height of the block, which is also the number of this particular block in the blockchain.

pub fn tx_count(&self) -> u32

Number of transactions in this block.

pub fn prev_hash(&self) -> &Hash

Hash link to the previous block in the blockchain.

pub fn tx_hash(&self) -> &Hash

Root hash of the Merkle tree of transactions in this block.

pub fn state_hash(&self) -> &Hash

Hash of the blockchain state after applying transactions in the block.

Trait Implementations

impl Clone for Block

fn clone(&self) -> Block

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Eq for Block

impl Ord for Block

fn cmp(&self, other: &Block) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<Block> for Block

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

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

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

This method tests for !=.

impl PartialOrd<Block> for Block

fn partial_cmp(&self, other: &Block) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Block) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Block) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Block) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Block) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Debug for Block

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

Formats the value using the given formatter.

impl StructuralPartialEq for Block

impl StructuralEq for Block

impl Serialize for Block

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

Serialize this value into the given Serde serializer.

impl<'de> Deserialize<'de> for Block

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl BinaryValue for Block

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

Serializes the given value to the vector of bytes.

fn from_bytes(value: Cow<[u8]>) -> Result<Self, Error>

Deserializes the value from the given bytes array.

fn into_bytes(self) -> Vec<u8>

Consumes and serializes the given value to the vector of bytes. This method is faster with the wrapped values, thus if you wouldn't use value after serialization use it.

impl ObjectHash for Block

fn object_hash(&self) -> Hash

Returns a hash of the value.

impl ProtobufConvert for Block

type ProtoStruct = Block

Type of the protobuf clone of Self

fn from_pb(pb: Self::ProtoStruct) -> Result<Self, Error>

ProtoStruct -> Struct

fn to_pb(&self) -> Self::ProtoStruct

Struct -> ProtoStruct
