Struct bp_header_chain::StoredHeaderData

pub struct StoredHeaderData<Number, Hash> {
    pub number: Number,
    pub state_root: Hash,
}

Header data that we’re storing on-chain.

Even though we may store full header, our applications (XCM) only use couple of header fields. Extracting those values makes on-chain storage and PoV smaller, which is good.

Fields

number: Number

Header number.

state_root: Hash

Header state root.

Trait Implementations

impl<Number: Clone, Hash: Clone> Clone for StoredHeaderData<Number, Hash>

fn clone(&self) -> StoredHeaderData<Number, Hash>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Number, Hash> Debug for StoredHeaderData<Number, Hash>where Number: Debug, Hash: Debug,

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

Formats the value using the given formatter.

impl<Number, Hash> Decode for StoredHeaderData<Number, Hash>where Number: Decode, Hash: Decode,

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

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<Number, Hash> Encode for StoredHeaderData<Number, Hash>where Number: Encode, Hash: Encode,

fn size_hint(&self) -> usize

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

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

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

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

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<Number, Hash> MaxEncodedLen for StoredHeaderData<Number, Hash>where Number: MaxEncodedLen, Hash: MaxEncodedLen,

fn max_encoded_len() -> usize

Upper bound, in bytes, of the maximum encoded size of this item.

impl<Number: PartialEq, Hash: PartialEq> PartialEq for StoredHeaderData<Number, Hash>

fn eq(&self, other: &StoredHeaderData<Number, Hash>) -> 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<Number, Hash> TypeInfo for StoredHeaderData<Number, Hash>where Number: TypeInfo + 'static, Hash: TypeInfo + 'static,

type Identity = StoredHeaderData<Number, Hash>

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
