Implementations

impl BlockHeader

pub fn compute_block_hash(&self, crypto: &dyn Crypto) -> H256

pub fn hash(&self) -> H256

Trait Implementations

impl Archive for BlockHeader

where Skip: ArchiveWith<OnceCell<BlockHash>>, H256Wrapper: ArchiveWith<H256>, H160Wrapper: ArchiveWith<Address>, BloomWrapper: ArchiveWith<Bloom>, U256Wrapper: ArchiveWith<U256>, BlockNumber: Archive, u64: Archive, BytesWrapper: ArchiveWith<Bytes>, Option<u64>: Archive, OptionH256Wrapper: ArchiveWith<Option<H256>>,

type Archived = ArchivedBlockHeader

The archived representation of this type.

type Resolver = BlockHeaderResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve(&self, resolver: Self::Resolver, out: Place<Self::Archived>)

Creates the archived version of this value at the given position and writes it to the given output.

const COPY_OPTIMIZATION: CopyOptimization<Self> = _

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

impl Clone for BlockHeader

fn clone(&self) -> BlockHeader

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BlockHeader

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for BlockHeader

fn default() -> BlockHeader

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for BlockHeader

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<__D: Fallible + ?Sized> Deserialize<BlockHeader, __D> for Archived<BlockHeader>

where Skip: ArchiveWith<OnceCell<BlockHash>> + DeserializeWith<<Skip as ArchiveWith<OnceCell<BlockHash>>>::Archived, OnceCell<BlockHash>, __D>, H256Wrapper: ArchiveWith<H256> + DeserializeWith<<H256Wrapper as ArchiveWith<H256>>::Archived, H256, __D>, H160Wrapper: ArchiveWith<Address> + DeserializeWith<<H160Wrapper as ArchiveWith<Address>>::Archived, Address, __D>, BloomWrapper: ArchiveWith<Bloom> + DeserializeWith<<BloomWrapper as ArchiveWith<Bloom>>::Archived, Bloom, __D>, U256Wrapper: ArchiveWith<U256> + DeserializeWith<<U256Wrapper as ArchiveWith<U256>>::Archived, U256, __D>, BlockNumber: Archive, <BlockNumber as Archive>::Archived: Deserialize<BlockNumber, __D>, u64: Archive, <u64 as Archive>::Archived: Deserialize<u64, __D>, BytesWrapper: ArchiveWith<Bytes> + DeserializeWith<<BytesWrapper as ArchiveWith<Bytes>>::Archived, Bytes, __D>, Option<u64>: Archive, <Option<u64> as Archive>::Archived: Deserialize<Option<u64>, __D>, OptionH256Wrapper: ArchiveWith<Option<H256>> + DeserializeWith<<OptionH256Wrapper as ArchiveWith<Option<H256>>>::Archived, Option<H256>, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<BlockHeader, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl Eq for BlockHeader

impl PartialEq for BlockHeader

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl RLPDecode for BlockHeader

fn decode_unfinished(rlp: &[u8]) -> Result<(Self, &[u8]), RLPDecodeError>

fn decode(rlp: &[u8]) -> Result<Self, RLPDecodeError>

impl RLPEncode for BlockHeader

fn encode(&self, buf: &mut dyn BufMut)

fn length(&self) -> usize

fn encode_to_vec(&self) -> Vec<u8>

impl Serialize for BlockHeader

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<__S: Fallible + ?Sized> Serialize<__S> for BlockHeader

where Skip: SerializeWith<OnceCell<BlockHash>, __S>, H256Wrapper: SerializeWith<H256, __S>, H160Wrapper: SerializeWith<Address, __S>, BloomWrapper: SerializeWith<Bloom, __S>, U256Wrapper: SerializeWith<U256, __S>, BlockNumber: Serialize<__S>, u64: Serialize<__S>, BytesWrapper: SerializeWith<Bytes, __S>, Option<u64>: Serialize<__S>, OptionH256Wrapper: SerializeWith<Option<H256>, __S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.
