Variants

InvalidStateRoot

Attempted to create a trie with a state root not in the DB.

IncompleteDatabase

Trie item not found in the database,

ValueAtIncompleteKey

A value was found in the trie with a nibble key that was not byte-aligned.

DecoderError

Corrupt Trie item.

InvalidHash

Hash is not value.

DuplicateKey

The statement being verified contains multiple key-value pairs with the same key.

ExtraneousNode

The proof contains at least one extraneous node.

ExtraneousValue

The proof contains at least one extraneous value which should have been omitted from the proof.

ExtraneousHashReference

The proof contains at least one extraneous hash reference the should have been omitted.

InvalidChildReference

The proof contains an invalid child reference that exceeds the hash length.

ValueMismatch

The proof indicates that an expected value was not found in the trie.

IncompleteProof

The proof is missing trie nodes required to verify.

RootMismatch

The root hash computed from the proof is incorrect.

DecodeError

One of the proof nodes could not be decoded.

Trait Implementations

impl Clone for TrieError

fn clone(&self) -> TrieError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TrieError

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

Formats the value using the given formatter.

impl Decode for TrieError

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

where __CodecInputEdqy: Input,

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<'de> Deserialize<'de> for TrieError

fn deserialize<__D>( __deserializer: __D, ) -> Result<TrieError, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encode for TrieError

fn size_hint(&self) -> usize

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

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>

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<T, U> From<Error<T, U>> for TrieError

fn from(error: Error<T, U>) -> TrieError

Converts to this type from the input type.

impl<T> From<TrieError<T, Error<T>>> for TrieError

fn from(error: TrieError<T, Error<T>>) -> TrieError

Converts to this type from the input type.

impl From<TrieError> for &'static str

fn from(e: TrieError) -> &'static str

Converts to this type from the input type.

impl From<TrieError> for DispatchError

fn from(e: TrieError) -> DispatchError

Converts to this type from the input type.

impl MaxEncodedLen for TrieError

fn max_encoded_len() -> usize

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

impl PartialEq for TrieError

fn eq(&self, other: &TrieError) -> 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.

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TypeInfo for TrieError

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.

impl Copy for TrieError

impl EncodeLike for TrieError

impl Eq for TrieError

impl StructuralPartialEq for TrieError
