Enum TokenError

pub enum TokenError {
    FundsUnavailable,
    OnlyProvider,
    BelowMinimum,
    CannotCreate,
    UnknownAsset,
    Frozen,
    Unsupported,
    CannotCreateHold,
    NotExpendable,
    Blocked,
}

An error relating to tokens when dispatching a transaction.

Variants

FundsUnavailable

Funds are unavailable.

OnlyProvider

Some part of the balance gives the only provider reference to the account and thus cannot be (re)moved.

BelowMinimum

Account cannot exist with the funds that would be given.

CannotCreate

Account cannot be created.

UnknownAsset

The asset in question is unknown.

Frozen

Funds exist but are frozen.

Unsupported

Operation is not supported by the asset.

CannotCreateHold

Account cannot be created for a held balance.

NotExpendable

Withdrawal would cause unwanted loss of account.

Blocked

Account cannot receive the assets.

Trait Implementations

impl Clone for TokenError

fn clone(&self) -> TokenError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TokenError

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

Formats the value using the given formatter.

impl Decode for TokenError

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 TokenError

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<TokenError> for DispatchError

fn from(value: TokenError) -> Self

Converts to this type from the input type.

impl IntoVisitor for TokenError

type AnyVisitor<ScaleDecodeTypeResolver: TypeResolver> = Visitor<ScaleDecodeTypeResolver>

The visitor type used to decode SCALE encoded bytes to Self.

fn into_visitor<ScaleDecodeTypeResolver: TypeResolver>() -> Self::AnyVisitor<ScaleDecodeTypeResolver>

A means of obtaining this visitor.

impl PartialEq for TokenError

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