Implementations

impl PooledTransactionsElement

pub fn try_from_broadcast( tx: TransactionSigned, ) -> Result<Self, TransactionSigned>

Tries to convert a TransactionSigned into a PooledTransactionsElement.

This function used as a helper to convert from a decoded p2p broadcast message to PooledTransactionsElement. Since BlobTransaction is disallowed to be broadcasted on p2p, return an err if tx is Transaction::Eip4844.

Converts from an EIP-4844 TransactionSignedEcRecovered to a PooledTransactionsElementEcRecovered with the given sidecar.

Returns an Err containing the original TransactionSigned if the transaction is not EIP-4844.

pub fn signature_hash(&self) -> B256

pub const fn max_fee_per_blob_gas(&self) -> Option<u128>

Max fee per blob gas for eip4844 transaction [TxEip4844].
