Struct Block

pub struct Block<T = TransactionSigned> {
    pub header: Header,
    pub body: BlockBody<T>,
}

Ethereum full block.

Withdrawals can be optionally included at the end of the RLP encoded message.

Fields

header: Header

Block header.

body: BlockBody<T>

Block body.

Methods from Deref<Target = Header>

pub fn hash_slow(&self) -> FixedBytes<32>

Heavy function that will calculate hash of data and will not save the change to metadata.

Use Header::seal_slow and unlock if you need the hash to be persistent.

pub fn ommers_hash_is_empty(&self) -> bool

Check if the ommers hash equals to empty hash list.

pub fn transaction_root_is_empty(&self) -> bool

Check if the transaction root equals to empty root.

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

Returns the blob fee for this block according to the EIP-4844 spec.

Returns None if excess_blob_gas is None

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

Returns the blob fee for the next block according to the EIP-4844 spec.

Returns None if excess_blob_gas is None.

See also Self::next_block_excess_blob_gas

pub fn next_block_base_fee(&self, base_fee_params: BaseFeeParams) -> Option<u64>

Calculate base fee for next block according to the EIP-1559 spec.

Returns a None if no base fee is set, no EIP-1559 support

pub fn next_block_excess_blob_gas(&self) -> Option<u64>

Calculate excess blob gas for the next block according to the EIP-4844 spec.

If Self::target_blobs_per_block is Some, uses EIP-7742 formula for calculating the excess blob gas, otherwise uses EIP-4844 formula.

Returns a None if no excess blob gas is set, no EIP-4844 support

pub fn size(&self) -> usize

Calculate a heuristic for the in-memory size of the Header.

pub fn parent_num_hash(&self) -> NumHash

Returns the parent block’s number and hash

Note: for the genesis block the parent number is 0 and the parent hash is the zero hash.

pub fn num_hash_slow(&self) -> NumHash

Returns the block’s number and hash.

Note: this hashes the header.

pub fn num_hash_with_parent_slow(&self) -> BlockWithParent

Returns the block’s number and hash with the parent hash.

Note: this hashes the header.

fn decode(b: &mut &[u8]) -> Result<Block<T>, Error>

Decodes the blob into the appropriate type. buf must be advanced past the decoded object.

impl<T> Default for Block<T>

fn default() -> Block<T>

Returns the “default value” for a type.

impl<T> Deref for Block<T>

type Target = Header

The resulting type after dereferencing.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
