Enum frame_support::pallet_prelude::DispatchError

pub enum DispatchError {
    Other(&'static str),
    CannotLookup,
    BadOrigin,
    Module(ModuleError),
    ConsumerRemaining,
    NoProviders,
    TooManyConsumers,

    Transactional(TransactionalError),
    Exhausted,
    Corruption,
    Unavailable,
}

Reason why a dispatch call failed.

Variants

Other(&'static str)

Some error occurred.

CannotLookup

Failed to lookup some data.

BadOrigin

A bad origin.

Module(ModuleError)

A custom error in a module.

ConsumerRemaining

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

NoProviders

There are no providers so the account cannot be created.

TooManyConsumers

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

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

Corruption

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

Unavailable

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

Implementations

impl DispatchError

pub fn stripped(self) -> DispatchError

Return the same error but without the attached message.

Trait Implementations

impl Clone for DispatchError

fn clone(&self) -> DispatchError

Returns a copy of the value.

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

    __codec_input_edqy: &mut __CodecInputEdqy
) -> Result<DispatchError, Error>where
    __CodecInputEdqy: Input,

impl<'de> Deserialize<'de> for DispatchError

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

Deserialize this value from the given Serde deserializer.

impl Encode for DispatchError

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 size_hint(&self) -> usize

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

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.

Calculates the encoded size.

impl From<&'static str> for DispatchError

fn from(err: &'static str) -> DispatchError

Converts to this type from the input type.

impl From<ArithmeticError> for DispatchError

fn from(e: ArithmeticError) -> DispatchError

Converts to this type from the input type.

impl From<BadOrigin> for DispatchError

fn from(_: BadOrigin) -> DispatchError

Converts to this type from the input type.

impl From<DispatchError> for &'static str

fn from(err: DispatchError) -> &'static str

Converts to this type from the input type.

impl From<DispatchError> for Result<(), DispatchError>

fn from(err: DispatchError) -> Result<(), DispatchError>

Converts to this type from the input type.

impl From<LookupError> for DispatchError

fn from(_: LookupError) -> DispatchError

Converts to this type from the input type.

Converts to this type from the input type.

impl From<TransactionalError> for DispatchError

fn from(e: TransactionalError) -> DispatchError

Converts to this type from the input type.

impl MaxEncodedLen for DispatchError

fn max_encoded_len() -> usize

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

impl PartialEq<DispatchError> for DispatchError

fn eq(&self, other: &DispatchError) -> 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 Printable for DispatchError

fn print(&self)

Print the object.

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