Struct GasBreakdown 

pub struct GasBreakdown {
    pub execution_gas_cost: U256,
    pub blob_gas_cost: U256,
    pub l1_data_fee: U256,
    pub blob_count: BlobCount,
    pub blob_gas_price: BlobGasPrice,
}

Detailed breakdown of gas costs for a transaction

Separates execution gas, blob gas, and L1 data fees for comprehensive analytics and cost attribution.

Example

use alloy_primitives::U256;
use semioscan::{GasBreakdown, BlobGasPrice};

let breakdown = GasBreakdown::builder()
    .execution_gas_cost(U256::from(1_000_000_000_000_000u64))
    .blob_gas_cost(U256::from(500_000_000_000_000u64))
    .build();

assert_eq!(
    breakdown.total_cost(),
    U256::from(1_500_000_000_000_000u64)
);

Fields

execution_gas_cost: U256

Cost for regular execution gas (gas_used * effective_gas_price)

blob_gas_cost: U256

Cost for blob gas (blob_gas_used * blob_gas_price) - EIP-4844 only

l1_data_fee: U256

L1 data fee for OP-stack chains (Optimism, Base, etc.)

blob_count: BlobCount

Number of blobs in the transaction (0 for non-EIP-4844)

blob_gas_price: BlobGasPrice

Blob gas price used for this transaction

Implementations

impl GasBreakdown

pub const fn new() -> Self

Create a new empty gas breakdown

pub fn builder() -> GasBreakdownBuilder

Create a builder for constructing a gas breakdown

pub fn total_cost(&self) -> U256

Calculate total cost (execution + blob + L1 data fee)

pub fn has_blob_gas(&self) -> bool

Check if this transaction used blob gas (is EIP-4844)

pub fn has_l1_data_fee(&self) -> bool

Check if this transaction has L1 data fees (is on an L2)

pub fn merge(&mut self, other: &Self)

Merge another breakdown into this one (for aggregation)

Trait Implementations

impl Add for GasBreakdown

type Output = GasBreakdown

The resulting type after applying the + operator.

fn add(self, rhs: Self) -> Self::Output

Performs the + operation.

impl Clone for GasBreakdown

fn clone(&self) -> GasBreakdown

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GasBreakdown

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

Formats the value using the given formatter.

impl Default for GasBreakdown

fn default() -> GasBreakdown

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for GasBreakdown

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for GasBreakdown

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

Formats the value using the given formatter.

impl PartialEq for GasBreakdown

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
