Struct reth_primitives_traits::header::SealedHeader
source · pub struct SealedHeader { /* private fields */ }
Expand description
A Header
that is sealed at a precalculated hash, use SealedHeader::unseal()
if you want
to modify header.
Implementations§
source§impl SealedHeader
impl SealedHeader

source§impl SealedHeader
impl SealedHeader

which returns the raw header and hash.
sourcepub fn size(&self) -> usize
pub fn size(&self) -> usize
Calculates a heuristic for the in-memory size of the SealedHeader
.

Methods from Deref<Target = Header>§
sourcepub fn is_zero_difficulty(&self) -> bool
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.
sourcepub fn ensure_extradata_valid(&self) -> Result<(), HeaderError>
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.
sourcepub fn ensure_difficulty_valid(&self) -> Result<(), HeaderError>
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.
sourcepub fn ensure_well_formed(&self) -> Result<(), HeaderError>
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.
sourcepub fn is_timestamp_in_past(&self, parent_timestamp: u64) -> bool
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.
sourcepub fn exceeds_allowed_future_timestamp(&self, present_timestamp: u64) -> bool
pub fn exceeds_allowed_future_timestamp(&self, present_timestamp: u64) -> bool
Checks if the block’s timestamp is in the future based on the present timestamp.
Clock can drift but this can be consensus issue.
Note: This check is relevant only pre-merge.
sourcepub fn parent_num_hash(&self) -> BlockNumHash
pub fn parent_num_hash(&self) -> BlockNumHash
Returns the parent block’s number and hash
sourcepub fn hash_slow(&self) -> B256
pub fn hash_slow(&self) -> B256
Heavy function that will calculate hash of data and will not save the change to metadata.
Use Header::seal
, SealedHeader
and unlock if you need hash to be persistent.
sourcepub fn is_empty(&self) -> bool
pub fn is_empty(&self) -> bool
Checks if the header is empty - has no transactions and no ommers
sourcepub fn ommers_hash_is_empty(&self) -> bool
pub fn ommers_hash_is_empty(&self) -> bool
Check if the ommers hash equals to empty hash list.
sourcepub fn transaction_root_is_empty(&self) -> bool
pub fn transaction_root_is_empty(&self) -> bool
Check if the transaction root equals to empty root.
sourcepub fn blob_fee(&self) -> Option<u128>
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
sourcepub fn next_block_blob_fee(&self) -> Option<u128>
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
sourcepub fn next_block_base_fee(&self, base_fee_params: BaseFeeParams) -> Option<u64>
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
sourcepub fn next_block_excess_blob_gas(&self) -> Option<u64>
pub fn next_block_excess_blob_gas(&self) -> Option<u64>
Calculate excess blob gas for the next block according to the EIP-4844 spec.
Returns a None
if no excess blob gas is set, no EIP-4844 support
