Implementations

impl Header

pub fn compute_hash(&self) -> H256

Compute hash of this header (keccak of the RLP with seal).

pub fn compute_partial_hash(&self) -> H256

Compute hash of the truncated header i.e. excluding seal.

pub fn check_receipt_proof( &self, proof: &[Vec<u8, Global>] ) -> Option<Result<Receipt, DecoderError>>

pub fn apply_merkle_proof( &self, proof: &[Vec<u8, Global>] ) -> Option<(H256, Vec<u8, Global>)>

pub fn mix_hash(&self) -> Option<H256>

pub fn nonce(&self) -> Option<H64>

pub fn has_ommers(&self) -> bool

Trait Implementations

impl Clone for Header

fn clone(&self) -> Header

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Header

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

Formats the value using the given formatter.

impl Decode for Header

fn decode<__CodecInputEdqy>( __codec_input_edqy: &mut __CodecInputEdqy ) -> Result<Header, Error>where __CodecInputEdqy: Input,

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self> ) -> Result<DecodeFinished, Error>where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

fn skip<I>(input: &mut I) -> Result<(), Error>where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl Default for Header

fn default() -> Header

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Header

fn deserialize<__D>( __deserializer: __D ) -> Result<Header, <__D as Deserializer<'de>>::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encode for Header

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy )where __CodecOutputEdqy: Output + ?Sized,

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8, Global>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> Rwhere F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl PartialEq<Header> for Header

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for Header

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

Serialize this value into the given Serde serializer.

impl TypeInfo for Header

type Identity = Header

The type identifying for which type info is provided.

fn type_info() -> Type<MetaForm>

Returns the static type identifier for Self.

impl EncodeLike<Header> for Header

impl Eq for Header

impl StructuralEq for Header

impl StructuralPartialEq for Header
