Struct BlobParams

pub struct BlobParams {
    pub target_blob_count: u64,
    pub max_blob_count: u64,
    pub update_fraction: u128,
    pub min_blob_fee: u128,

Configuration for the blob-related calculations.

Fields

target_blob_count: u64

Target blob count for the block.

max_blob_count: u64

Max blob count for the block.

update_fraction: u128

Update fraction for excess blob gas calculation.

min_blob_fee: u128

Minimum gas price for a data blob.

Not required per EIP-7840 and assumed to be the default eip4844::BLOB_TX_MIN_BLOB_GASPRICE if not set.

max_blobs_per_tx: u64

Maximum number of blobs per transaction.

Defaults to max_blob_count unless set otherwise.

blob_base_cost: u64

Minimum execution gas required to include a blob in a block.

Defaults to 0 unless set otherwise.

Implementations

impl BlobParams

pub const fn cancun() -> Self

Returns BlobParams configuration activated with Cancun hardfork.

pub const fn prague() -> Self

Returns BlobParams configuration activated with Prague hardfork.

pub const fn osaka() -> Self

Returns BlobParams configuration activated with Osaka hardfork.

pub const fn bpo1() -> Self

BlobParams for the EIP-7892 Blob parameter only hardfork BPO1.

pub const fn bpo2() -> Self

BlobParams for the EIP-7892 Blob parameter only hardfork BPO2

pub const fn with_max_blobs_per_tx(self, max_blobs_per_tx: u64) -> Self

Set max blobs per transaction on BlobParams.

pub const fn with_blob_base_cost(self, blob_base_cost: u64) -> Self

Set blob base cost on BlobParams.

pub const fn max_blob_gas_per_block(&self) -> u64

Returns the maximum available blob gas in a block.

This is max blob count * DATA_GAS_PER_BLOB

pub const fn target_blob_gas_per_block(&self) -> u64

Returns the blob gas target per block.

This is target blob count * DATA_GAS_PER_BLOB

pub const fn next_block_excess_blob_gas( &self, excess_blob_gas: u64, blob_gas_used: u64, ) -> u64

👎Deprecated: Use next_block_excess_blob_gas_osaka instead

Calculates the excess_blob_gas value for the next block based on the current block excess_blob_gas and blob_gas_used.

pub const fn next_block_excess_blob_gas_osaka( &self, excess_blob_gas: u64, blob_gas_used: u64, base_fee_per_gas: u64, ) -> u64

Calculates the excess_blob_gas value for the next block based on the current block excess_blob_gas, blob_gas_used and base_fee_per_gas.

pub const fn calc_blob_fee(&self, excess_blob_gas: u64) -> u128

Calculates the blob fee for block based on its excess_blob_gas.

Trait Implementations

impl Clone for BlobParams

fn clone(&self) -> BlobParams

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlobParams

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BlobParams

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for BlobParams

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
