Response type for eth_feeHistory

Fields

base_fee_per_gas: Vec<u128>

An array of block base fees per gas. This includes the next block after the newest of the returned range, because this value can be derived from the newest block. Zeroes are returned for pre-EIP-1559 blocks.

Note

Empty list is skipped only for compatibility with Erigon and Geth.

gas_used_ratio: Vec<f64>

An array of block gas used ratios. These are calculated as the ratio of gasUsed and gasLimit.

base_fee_per_blob_gas: Vec<u128>

An array of block base fees per blob gas. This includes the next block after the newest of the returned range, because this value can be derived from the newest block. Zeroes are returned for pre-EIP-4844 blocks.

blob_gas_used_ratio: Vec<f64>

An array of block blob gas used ratios. These are calculated as the ratio of gasUsed and gasLimit.

oldest_block: u64

Lowest number block of the returned range.

reward: Option<Vec<Vec<u128>>>

An (optional) array of effective priority fee per gas data points from a single block. All zeroes are returned if the block is empty.

Implementations

impl FeeHistory

pub fn latest_block_base_fee(&self) -> Option<u128>

Returns the base fee of the latest block in the eth_feeHistory request.

pub fn next_block_base_fee(&self) -> Option<u128>

Returns the base fee of the next block.

pub fn next_block_blob_base_fee(&self) -> Option<u128>

Returns the blob base fee of the next block.

If the next block is pre-EIP-4844, this will return None.

pub fn latest_block_blob_base_fee(&self) -> Option<u128>

Returns the blob fee of the latest block in the eth_feeHistory request.

If the next block is pre-EIP-4844, this will return None.

Trait Implementations

impl Clone for FeeHistory

fn clone(&self) -> FeeHistory

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FeeHistory

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

Formats the value using the given formatter.

impl Default for FeeHistory

fn default() -> FeeHistory

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FeeHistory

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for FeeHistory

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
