Struct common_types::encoded::Header
source · [−]pub struct Header(_);Expand description
Owning header view.
Implementations
sourceimpl Header
impl Header
sourcepub fn new(encoded: Vec<u8>) -> Self
pub fn new(encoded: Vec<u8>) -> Self
Create a new owning header view. Expects the data to be an RLP-encoded header – any other case will likely lead to panics further down the line.
sourcepub fn decode(
&self,
eip1559_transition: BlockNumber
) -> Result<FullHeader, DecoderError>
pub fn decode(
&self,
eip1559_transition: BlockNumber
) -> Result<FullHeader, DecoderError>
Upgrade this encoded view to a fully owned Header object.
sourcepub fn view(&self) -> HeaderView<'_>
pub fn view(&self) -> HeaderView<'_>
Get a borrowed header view onto the data.
sourcepub fn into_inner(self) -> Vec<u8>
pub fn into_inner(self) -> Vec<u8>
Consume the view and return the raw bytes.
sourceimpl Header
impl Header
sourcepub fn parent_hash(&self) -> H256
pub fn parent_hash(&self) -> H256
Returns the parent hash.
sourcepub fn uncles_hash(&self) -> H256
pub fn uncles_hash(&self) -> H256
Returns the uncles hash.
Returns the author.
sourcepub fn state_root(&self) -> H256
pub fn state_root(&self) -> H256
Returns the state root.
sourcepub fn transactions_root(&self) -> H256
pub fn transactions_root(&self) -> H256
Returns the transaction trie root.
sourcepub fn receipts_root(&self) -> H256
pub fn receipts_root(&self) -> H256
Returns the receipts trie root
sourcepub fn difficulty(&self) -> U256
pub fn difficulty(&self) -> U256
Difficulty of this block
sourcepub fn number(&self) -> BlockNumber
pub fn number(&self) -> BlockNumber
Number of this block.
sourcepub fn extra_data(&self) -> Vec<u8>
pub fn extra_data(&self) -> Vec<u8>
Block extra data.
Trait Implementations
sourceimpl MallocSizeOf for Header
impl MallocSizeOf for Header
sourcefn size_of(&self, ops: &mut MallocSizeOfOps) -> usize
fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize
Measure the heap usage of all descendant heap-allocated structures, but
not the space taken up by the value itself.
If T::size_of is a constant, consider implementing constant_size as well. Read more
sourcefn constant_size() -> Option<usize>
fn constant_size() -> Option<usize>
Used to optimize MallocSizeOf implementation for collections
like Vec and HashMap to avoid iterating over them unnecessarily.
The Self: Sized bound is for object safety. Read more
