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>(
    &self,
    expected_root: Option<&<H as Hasher>::Out>
) -> Result<(StorageProof, <H as Hasher>::Out), Error<<H as Hasher>::Out, Error<<H as Hasher>::Out>>>where
    H: Hasher,

Decode to a full storage_proof.

pub fn to_memory_db<H>(
    &self,
    expected_root: Option<&<H as Hasher>::Out>
) -> Result<(MemoryDB<H, HashKey<H>, Vec<u8, Global>, NoopTracker<Vec<u8, Global>>>, <H as Hasher>::Out), Error<<H as Hasher>::Out, Error<<H as Hasher>::Out>>>where
    H: Hasher,

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<(), Error>

Formats the value using the given formatter.

impl Decode for CompactProof

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

Attempt to deserialise the value from input.

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 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 size_hint(&self) -> usize

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

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl PartialEq<CompactProof> 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<MetaForm>

Returns the static type identifier for Self.
