Struct sp_transaction_storage_proof::TransactionStorageProof

pub struct TransactionStorageProof {
    pub chunk: Vec<u8>,
    pub proof: Vec<Vec<u8>>,
}

Holds a chunk of data retrieved from storage along with a proof that the data was stored at that location in the trie.

Fields

chunk: Vec<u8>

Data chunk that is proved to exist.

proof: Vec<Vec<u8>>

Trie nodes that compose the proof.

Trait Implementations

impl Clone for TransactionStorageProof

fn clone(&self) -> TransactionStorageProof

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TransactionStorageProof

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

Formats the value using the given formatter.

impl Decode for TransactionStorageProof

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 Encode for TransactionStorageProof

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

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

fn size_hint(&self) -> usize

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

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<TransactionStorageProof> for TransactionStorageProof

fn eq(&self, other: &TransactionStorageProof) -> 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 TypeInfo for TransactionStorageProof

type Identity = TransactionStorageProof

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
