Enum TokenError 

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

An error relating to tokens when 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.

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 Debug for TokenError

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

Formats the value using the given formatter.

impl Display for TokenError

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

Formats the value using the given formatter.

impl Error for TokenError

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 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.
