Struct sp_trie::CompactProof

pub struct CompactProof {
    pub encoded_nodes: Vec<Vec<u8>>,
}

Storage proof in compact form.

Fields

encoded_nodes: Vec<Vec<u8>>

Implementations

impl CompactProof

pub fn iter_compact_encoded_nodes(&self) -> impl Iterator<Item = &[u8]>

Return an iterator on the compact encoded nodes.

pub fn to_storage_proof<H: Hasher>( &self, expected_root: Option<&H::Out>, ) -> Result<(StorageProof, H::Out), CompactProofError<H::Out, Error<H::Out>>>

Decode to a full storage_proof.

pub fn to_memory_db<H: Hasher>( &self, expected_root: Option<&H::Out>, ) -> Result<(MemoryDB<H>, H::Out), CompactProofError<H::Out, Error<H::Out>>>

Convert self into a MemoryDB.

expected_root is the expected root of this compact proof.

Returns the memory db and the root of the trie.

Trait Implementations

impl Clone for CompactProof

fn clone(&self) -> CompactProof

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CompactProof

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

Formats the value using the given formatter.

impl Decode for CompactProof

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 CompactProof

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<__CodecOutputReturn, __CodecUsingEncodedCallback: FnOnce(&[u8]) -> __CodecOutputReturn>( &self, f: __CodecUsingEncodedCallback, ) -> __CodecOutputReturn

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

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl PartialEq for CompactProof

fn eq(&self, other: &CompactProof) -> 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 CompactProof

type Identity = CompactProof

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
