Enum DispatchError

pub enum DispatchError {
    Other(&'static str),
    CannotLookup,
    BadOrigin,
    Module {
        index: u8,
        error: u8,
        message: Option<&'static str>,
    },
    ConsumerRemaining,
    NoProviders,
}

Reason why a dispatch call failed.

Variants

Other(&'static str)

Some error occurred.

CannotLookup

Failed to lookup some data.

BadOrigin

A bad origin.

Module

A custom error in a module.

Fields

index: u8

Module index, matching the metadata module index.

error: u8

Module specific error value.

message: Option<&'static str>

Optional error message.

ConsumerRemaining

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

NoProviders

There are no providers so the account cannot be created.

Implementations

impl DispatchError

pub fn stripped(self) -> Self

Return the same error but without the attached message.

Trait Implementations

impl Clone for DispatchError

fn clone(&self) -> DispatchError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DispatchError

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

Formats the value using the given formatter.

impl Decode for DispatchError

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy, ) -> Result<Self, Error>

Attempt to deserialise the value from input.

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 DispatchError

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encode for DispatchError

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy, )

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>

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<&'static str> for DispatchError

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

Converts to this type from the input type.

impl From<BadOrigin> for DispatchError

fn from(_: BadOrigin) -> Self

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 DispatchOutcome

fn from(err: DispatchError) -> Self

Converts to this type from the input type.

impl From<LookupError> for DispatchError

fn from(_: LookupError) -> Self

Converts to this type from the input type.

impl From<StoredMapError> for DispatchError

fn from(e: StoredMapError) -> 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.

impl Printable for DispatchError

fn print(&self)

Print the object.

impl Serialize for DispatchError

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for DispatchError

impl EncodeLike for DispatchError

impl Eq for DispatchError
