Struct BlockMetadata 

pub struct BlockMetadata {
    pub gas_used: u64,
    pub gas_limit: u64,
    pub tx_count: u64,
    pub protocol_version: u32,
    pub base_fee_per_gas: Option<u128>,
}

Additional metadata included in a block header

Fields

gas_used: u64

Total gas used in this block

gas_limit: u64

Gas limit for this block

tx_count: u64

Number of transactions in this block

protocol_version: u32

Protocol version

base_fee_per_gas: Option<u128>

EIP-1559 base fee per gas for this block, in wei-equivalent (TNZO base units / 10^18).

Stamped at block-finalize time from the live FeeMarket. This is the minimum gas price that any transaction in this block had to bid; the portion of effective gas price equal to this is burned. eth_feeHistory reads this field directly per block, so it must be persisted with the block header rather than reconstructed from the runtime fee market (which only retains a bounded recent window).

None for genesis and any block produced before EIP-1559 wiring; new blocks always carry Some(_).

Trait Implementations

impl Clone for BlockMetadata

fn clone(&self) -> BlockMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlockMetadata

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

Formats the value using the given formatter.

impl Default for BlockMetadata

fn default() -> BlockMetadata

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for BlockMetadata

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for BlockMetadata

impl PartialEq for BlockMetadata

fn eq(&self, other: &BlockMetadata) -> 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 Serialize for BlockMetadata

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
