Expand description

A Header that is sealed at a precalculated hash, use SealedHeader::unseal() if you want to modify header.

Implementations§

pub const fn bitflag_unused_bits() -> usize

pub fn size(&self) -> usize

Calculates a heuristic for the in-memory size of the SealedHeader.

Methods from Deref<Target = Header>§

pub fn is_zero_difficulty(&self) -> bool

Checks if the block’s difficulty is set to zero, indicating a Proof-of-Stake header.

This function is linked to EIP-3675, proposing the consensus upgrade to Proof-of-Stake: EIP-3675

Verifies whether, as per the EIP, the block’s difficulty is updated to zero, signifying the transition to a Proof-of-Stake mechanism.

Returns true if the block’s difficulty matches the constant zero set by the EIP.

pub fn ensure_extradata_valid(&self) -> Result<(), HeaderError>

Performs a sanity check on the extradata field of the header.

§Errors

Returns an error if the extradata size is larger than 100 KB.

pub fn ensure_difficulty_valid(&self) -> Result<(), HeaderError>

Performs a sanity check on the block difficulty field of the header.

§Errors

Returns an error if the block difficulty exceeds 80 bits.

pub fn ensure_well_formed(&self) -> Result<(), HeaderError>

Performs combined sanity checks on multiple header fields.

This method combines checks for block difficulty and extradata sizes.

§Errors

Returns an error if either the block difficulty exceeds 80 bits or if the extradata size is larger than 100 KB.

pub fn is_timestamp_in_past(&self, parent_timestamp: u64) -> bool

Checks if the block’s timestamp is in the past compared to the parent block’s timestamp.

Note: This check is relevant only pre-merge.

pub fn exceeds_allowed_future_timestamp(&self, present_timestamp: u64) -> bool

pub fn parent_num_hash(&self) -> BlockNumHash

Returns the parent block’s number and hash

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

pub fn is_empty(&self) -> bool

Checks if the header is empty - has no transactions and no ommers

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.
