Enum DispatchError

#[non_exhaustive]
pub enum DispatchError {
    Other,
    CannotLookup,
    BadOrigin,
    Module(ModuleError),
    ConsumerRemaining,
    NoProviders,
    TooManyConsumers,
    Token(TokenError),
    Arithmetic(ArithmeticError),
    Transactional(TransactionalError),
    Exhausted,
    Corruption,
    Unavailable,
    RootNotAllowed,
}

An error dispatching a transaction.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Other

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.

RootNotAllowed

Root origin is not allowed.

Trait Implementations

impl Debug for DispatchError

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

Formats the value using the given formatter.

impl Display for DispatchError

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

Formats the value using the given formatter.

impl Error for DispatchError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<DispatchError> for Error

fn from(source: DispatchError) -> Self

Converts to this type from the input type.

impl PartialEq for DispatchError

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