}

Errors that can occur when checking PoE Transactions

Variants

WrongNumberInputs

Wrong number of inputs were provided to the constraint checker.

WrongNumberOutputs

Wrong number of outputs were provided to the constraint checker.

BadlyTypedInput

An input data has the wrong type.

BadlyTypedOutput

An output data has the wrong type.

EffectiveHeightInPast

The effective height of this claim is in the past, So the claim cannot be created.

DisputingMismatchedClaims

Claims under dispute do not have the same hash, but they must.

IncorrectDisputeWinner

The winner of a dispute must be the oldest claim (the lowest block number)

Trait Implementations

impl Clone for ConstraintCheckerError

fn clone(&self) -> ConstraintCheckerError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ConstraintCheckerError

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

Formats the value using the given formatter.

impl Decode for ConstraintCheckerError

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<'de> Deserialize<'de> for ConstraintCheckerError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encode for ConstraintCheckerError

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 PartialEq for ConstraintCheckerError

fn eq(&self, other: &ConstraintCheckerError) -> 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 Serialize for ConstraintCheckerError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
