Errors that can occur when interacting with UnverifiedStorageProof and VerifiedStorageProof.

Variants

UnableToGenerateTrieProof

Call to generate_trie_proof() failed.

InvalidProof

Call to verify_trie_proof() failed.

UnsortedEntries

The Vec entries weren’t sorted as expected.

UnavailableKey

The provided key wasn’t found.

EmptyVal

The value associated to the provided key is None.

DecodeError

Error decoding value associated to a provided key.

UnusedKey

At least one key or node wasn’t read.

StorageRootMismatch

Expected storage root is missing from the proof. (for non-compact proofs)

StorageValueUnavailable

Unable to reach expected storage value using provided trie nodes. (for non-compact proofs)

DuplicateNodes

The proof contains duplicate nodes. (for non-compact proofs)

Trait Implementations

impl Clone for StorageProofError

fn clone(&self) -> StorageProofError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StorageProofError

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

Formats the value using the given formatter.

impl Decode for StorageProofError

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 StorageProofError

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) -> R

where 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 From<Error> for StorageProofError

fn from(e: Error) -> Self

Converts to this type from the input type.

impl From<StorageProofError> for StorageProofError

fn from(e: StorageProofError) -> Self

Converts to this type from the input type.

impl PalletError for StorageProofError

const MAX_ENCODED_SIZE: usize = 1usize
