Enum ArithmeticError

#[non_exhaustive]
pub enum ArithmeticError {
    Underflow,
    Overflow,
    DivisionByZero,
}

An error relating to arithmetic 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.

Underflow

Underflow.

Overflow

Overflow.

DivisionByZero

Division by zero.

Trait Implementations

impl Debug for ArithmeticError

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

Formats the value using the given formatter.

impl Display for ArithmeticError

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

Formats the value using the given formatter.

impl Error for ArithmeticError

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 ArithmeticError

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 ArithmeticError

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