Struct HeaderInfo

pub struct HeaderInfo {

    pub beneficiary: Address,

Essential info extracted from a header.

Fields

number: u64

The number of ancestor blocks of this block (block height).

beneficiary: Address

Beneficiary (Coinbase or miner) is a address that have signed the block.

This is the receiver address of all the gas spent in the block.

timestamp: u64

The timestamp of the block in seconds since the UNIX epoch

gas_limit: u64

The gas limit of the block

base_fee_per_gas: Option<u64>

The base fee per gas, added in the London upgrade with EIP-1559

excess_blob_gas: Option<u64>

A running total of blob gas consumed in excess of the target, prior to the block. Blocks with above-target blob gas consumption increase this value, blocks with below-target blob gas consumption decrease it (bounded at 0). This was added in EIP-4844.

blob_gas_used: Option<u64>

The total amount of blob gas consumed by the transactions within the block, added in EIP-4844.

difficulty: U256

The difficulty of the block

Unused after the Paris (AKA the merge) upgrade and replaced by prevrandao and expected to be 0.

mix_hash: Option<B256>

The output of the randomness beacon provided by the beacon chain

Replaces difficulty after the Paris (AKA the merge) upgrade with EIP-4399.

Note: prevrandao can be found in a block in place of mix_hash.

Trait Implementations

impl Clone for HeaderInfo

fn clone(&self) -> HeaderInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for HeaderInfo

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

Formats the value using the given formatter.

impl Default for HeaderInfo

fn default() -> HeaderInfo

Returns the “default value” for a type.

impl PartialEq for HeaderInfo

fn eq(&self, other: &HeaderInfo) -> 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.
