Custom dispatch errors of this pallet.

Variants

AncientHeader

Header is same height or older than finalized block (we don’t support forks).

MissingHeader

Header referenced in inclusion proof doesn’t exist, e.g. because it’s pruned or older than genesis.

MissingParentHeader

Header’s parent has not been imported.

DuplicateHeader

Header has already been imported.

HeaderNotFinalized

Header referenced in inclusion proof is not final yet.

HeaderOnStaleFork

Header is on a stale fork, i.e. it’s not a descendant of the latest finalized block

InvalidHeader

One or more header fields are invalid.

InvalidProof

Proof could not be applied / verified.

DecodeFailed

Log could not be decoded

NetworkNotFound

Unknown network id passed

NetworkAlreadyExists

Network with given id already registered

DifficultyTooLow

Difficulty is too low comparing to last blocks difficulty

NetworkStateInvalid

Network state is not suitable to proceed transacton

Unknown

This should never be returned - indicates a bug

ConsensusNotSupported

Unsupported consensus engine

InvalidSignature

Signature provided inside unsigned extrinsic is not correct

HeaderNotFound

Header not found for block number

Trait Implementations

impl<T: Clone> Clone for Error<T>

fn clone(&self) -> Error<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Config> Debug for Error<T>

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

Formats the value using the given formatter.

impl<T> Decode for Error<T>

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<T> Encode for Error<T>

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, 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<T: Config> From<Error<T>> for &'static str

fn from(err: Error<T>) -> &'static str

Converts to this type from the input type.

impl<T: Config> From<Error<T>> for DispatchError

fn from(err: Error<T>) -> Self

Converts to this type from the input type.

impl<T: Config> Into<u8> for Error<T>

fn into(self) -> u8

Converts this type into the (usually inferred) input type.

impl<T> PalletError for Error<T>

const MAX_ENCODED_SIZE: usize = 1usize

The maximum encoded size for the implementing type.

impl<T: PartialEq> PartialEq<Error<T>> for Error<T>

fn eq(&self, other: &Error<T>) -> 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<T> TypeInfo for Error<T>where PhantomData<T>: TypeInfo + 'static, T: 'static,

type Identity = Error<T>

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.

impl<T> EncodeLike<Error<T>> for Error<T>

impl<T> StructuralPartialEq for Error<T>
