Abstraction for block’s body.

This type is a container for everything that is included in a block except the header. For ethereum this includes transactions, ommers, and withdrawals.

Required Associated Types

type Transaction: SignedTransaction

Ordered list of signed transactions as committed in the block.

type OmmerHeader: BlockHeader

Ommer header type.

Required Methods

fn transactions(&self) -> &[Self::Transaction]

Returns reference to transactions in the block.

fn into_ethereum_body(self) -> BlockBody<Self::Transaction, Self::OmmerHeader>

A Convenience function to convert this type into the regular ethereum block body that consists of:

• Transactions
• Withdrawals
• Ommers

Note: This conversion can be incomplete. It is not expected that this Body is the same as [alloy_consensus::BlockBody] only that it can be converted into it which is useful for the eth_ RPC namespace (e.g. RPC block).

fn into_transactions(self) -> Vec<Self::Transaction>

Consume the block body and return a Vec of transactions.

fn withdrawals(&self) -> Option<&Withdrawals>

Returns block withdrawals if any.

fn ommers(&self) -> Option<&[Self::OmmerHeader]>

Returns block ommers if any.

Provided Methods

fn transactions_iter(&self) -> impl Iterator<Item = &Self::Transaction>

Returns an iterator over the transactions in the block.

fn transaction_by_hash( &self, hash: &FixedBytes<32>, ) -> Option<&Self::Transaction>

Returns the transaction with the matching hash.

This is a convenience function for transactions_iter().find()

fn contains_transaction(&self, hash: &FixedBytes<32>) -> bool

Returns true if the block body contains a transaction with the given hash.

This is a convenience function for transaction_by_hash().is_some()

fn clone_transactions(&self) -> Vec<Self::Transaction>

Clones the transactions in the block.

This is a convenience function for transactions().to_vec()

fn transaction_hashes_iter(&self) -> impl Iterator<Item = &FixedBytes<32>>

Returns an iterator over all transaction hashes in the block body.

fn transaction_count(&self) -> usize

Returns the number of the transactions in the block.

fn contains_transaction_type(&self, tx_type: u8) -> bool

Returns true if the block body contains a transaction of the given type.

fn calculate_tx_root(&self) -> FixedBytes<32>

Calculate the transaction root for the block body.

fn calculate_withdrawals_root(&self) -> Option<FixedBytes<32>>

Calculate the withdrawals root for the block body.

Returns Some(root) if withdrawals are present, otherwise None.

fn calculate_ommers_root(&self) -> Option<FixedBytes<32>>

Calculate the ommers root for the block body.

Returns Some(root) if ommers are present, otherwise None.

fn blob_gas_used(&self) -> u64

Calculates the total blob gas used by all EIP-4844 transactions in the block.

fn blob_versioned_hashes_iter(&self) -> impl Iterator<Item = &FixedBytes<32>>

Returns an iterator over all blob versioned hashes in the block body.

fn encoded_2718_transactions_iter(&self) -> impl Iterator<Item = Vec<u8>>

Returns an iterator over the encoded 2718 transactions.

This is also known as raw transactions.

See also [Encodable2718].

fn encoded_2718_transactions(&self) -> Vec<Bytes>

Returns a vector of encoded 2718 transactions.

This is also known as raw transactions.

See also [Encodable2718].

fn recover_signers(&self) -> Result<Vec<Address>, RecoveryError>

Recover signer addresses for all transactions in the block body.

fn try_recover_signers(&self) -> Result<Vec<Address>, RecoveryError>

Recover signer addresses for all transactions in the block body.

Returns an error if some transaction’s signature is invalid.

fn recover_signers_unchecked(&self) -> Result<Vec<Address>, RecoveryError>

Recover signer addresses for all transactions in the block body without ensuring that the signature has a low s value.

Returns RecoveryError, if some transaction’s signature is invalid.

fn try_recover_signers_unchecked(&self) -> Result<Vec<Address>, RecoveryError>

Recover signer addresses for all transactions in the block body without ensuring that the signature has a low s value.

Returns an error if some transaction’s signature is invalid.

fn recover_transactions( &self, ) -> Result<Vec<Recovered<Self::Transaction>>, RecoveryError>

Recovers signers for all transactions in the block body and returns a vector of [Recovered].

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
