Enum ArithError 

pub enum ArithError {
    Overflow,
    DivisionByZero,
    InvalidScale,
}

Why an arithmetic operation produced no value.

Variants

Overflow

The result, or a declared intermediate, does not fit in i128 units.

DivisionByZero

The divisor was zero.

InvalidScale

A requested scale was greater than SCALE.

impl Eq for ArithError

impl Error for ArithError

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 PartialEq for ArithError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
