Variants

Other

An unknown error occurred. This variant captures any unexpected errors that the contract cannot specifically handle. It is useful for cases where there are breaking changes in the runtime or when an error falls outside the predefined categories. The variant includes:

• dispatch_error_index: The index within the DispatchError.
• error_index: The index within the DispatchError variant (e.g. a TokenError).
• error: The specific error code or sub-index, providing additional context (e.g. error in ModuleError).

Fields

dispatch_error_index: u8

error_index: u8

error: u8

CannotLookup = 1

Failed to lookup some data.

BadOrigin = 2

A bad origin.

Module

A custom error in a module.

• index: The pallet index.
• error: The error within the pallet.

Fields

index: u8

error: u8

ConsumerRemaining = 4

At least one consumer is remaining so the account cannot be destroyed.

NoProviders = 5

There are no providers so the account cannot be created.

TooManyConsumers = 6

There are too many consumers so the account cannot be created.

Token(TokenError)

An error to do with tokens.

Arithmetic(ArithmeticError)

An arithmetic error.

Transactional(TransactionalError)

The number of transactional layers has been reached, or we are not in a transactional layer.

Exhausted = 10

Resources exhausted, e.g. attempt to read/write data which is too large to manipulate.

Corruption = 11

The state is corrupt; this is generally not going to fix itself.

Unavailable = 12

Some resource (e.g. a preimage) is unavailable right now. This might fix itself later.

RootNotAllowed = 13

Root origin is not allowed.

UnknownCall = 254

Unknown call.

DecodingFailed = 255

Decoding failed.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Decode for Error

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 Error

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<u32> for Error

fn from(value: u32) -> Self

Converts a u32 status code into an Error.

This conversion maps a raw status code returned by the runtime into the more descriptive Error enum variant, providing better context and understanding of the error.

impl PartialEq for Error

fn eq(&self, other: &Error) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TypeInfo for Error

type Identity = Error

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.

impl EncodeLike for Error

impl Eq for Error

impl StructuralPartialEq for Error
