Fields

chain: Option<Blockchain>

The blockchain network this block is part of.

hash: String

The unique identifier hash of the block.

number: u64

The block height/number in the blockchain.

parent_hash: String

Hash of the parent block.

miner: Ustr

Address of the miner or validator who produced this block.

gas_limit: u64

Maximum amount of gas allowed in this block.

gas_used: u64

Total gas actually used by all transactions in this block.

base_fee_per_gas: Option<U256>

EIP-1559 base fee per gas (wei); absent on pre-1559 or non-EIP chains.

Blob gas used in this block (EIP-4844); absent on chains without blobs.

excess_blob_gas: Option<U256>

Excess blob gas remaining after block execution (EIP-4844); None if not applicable.

l1_gas_price: Option<U256>

L1 gas price used for posting this block’s calldata (wei); Arbitrum only.

l1_gas_used: Option<u64>

L1 calldata gas units consumed when posting this block; Arbitrum only.

l1_fee_scalar: Option<u64>

Fixed-point (1e-6) scalar applied to the raw L1 fee; Arbitrum only.

timestamp: UnixNanos

Unix timestamp when the block was created.

Implementations

impl Block

pub fn new( hash: String, parent_hash: String, number: u64, miner: Ustr, gas_limit: u64, gas_used: u64, timestamp: UnixNanos, chain: Option<Blockchain>, ) -> Self

Creates a new Block instance with the specified properties.

pub fn chain(&self) -> Blockchain

Returns the blockchain for this block.

Panics

Panics if the chain has not been set.

pub fn set_chain(&mut self, chain: Blockchain)

pub fn with_base_fee(self, fee: U256) -> Self

Sets the EIP-1559 base fee and returns self for chaining.

pub fn with_blob_gas(self, used: U256, excess: U256) -> Self

Sets blob-gas metrics (EIP-4844) and returns self for chaining.

pub fn with_l1_fee_components( self, price: U256, gas_used: u64, scalar: u64, ) -> Self

Sets L1 fee components relevant for Arbitrum cost calculation and returns self for chaining.

Trait Implementations

impl Clone for Block

fn clone(&self) -> Block

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Block

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

Formats the value using the given formatter.

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 Display for Block

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

Formats the value using the given formatter.

impl<'py> IntoPyObject<'py> for Block

type Target = Block

The Python output type

type Output = Bound<'py, <Block as IntoPyObject<'py>>::Target>

The smart pointer type to use.

type Error = PyErr

The type returned in the event of a conversion error.

fn into_pyobject( self, py: Python<'py>, ) -> Result<<Self as IntoPyObject<'_>>::Output, <Self as IntoPyObject<'_>>::Error>

Performs the conversion.

impl PartialEq for Block

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PyClass for Block

type Frozen = False

Whether the pyclass is frozen.

impl PyClassImpl for Block

const IS_BASETYPE: bool = false

#[pyclass(subclass)]

const IS_SUBCLASS: bool = false

#[pyclass(extends=…)]

const IS_MAPPING: bool = false

#[pyclass(mapping)]

const IS_SEQUENCE: bool = false

#[pyclass(sequence)]

const IS_IMMUTABLE_TYPE: bool = false

#[pyclass(immutable_type)]

const RAW_DOC: &'static CStr = /// Represents an Ethereum-compatible blockchain block with essential metadata.

Docstring for the class provided on the struct or enum.

const DOC: &'static CStr

Fully rendered class doc, including the text_signature if a constructor is defined.

type BaseType = PyAny

Base class

type ThreadChecker = SendablePyClass<Block>

This handles following two situations:

type PyClassMutability = <<PyAny as PyClassBaseType>::PyClassMutability as PyClassMutability>::MutableChild

Immutable or mutable

type Dict = PyClassDummySlot

Specify this class has #[pyclass(dict)] or not.

type WeakRef = PyClassDummySlot

Specify this class has #[pyclass(weakref)] or not.

type BaseNativeType = PyAny

The closest native ancestor. This is PyAny by default, and when you declare #[pyclass(extends=PyDict)], it’s PyDict.
