Enum DecimalError 

pub enum DecimalError {
    CoefficientOutOfRange {
        spec: DecimalSpec,
    },
    ArithmeticOverflow,
    SpecMismatch {
        left: DecimalSpec,
        right: DecimalSpec,
    },
    LossyRescale {
        from_scale: u8,
        to_scale: u8,
    },
}

A safe decimal construction or arithmetic failure.

Variants

CoefficientOutOfRange

The coefficient does not fit the declared precision.

Fields

spec: DecimalSpec

The decimal type whose precision was exceeded.

ArithmeticOverflow

An i128 arithmetic operation overflowed.

SpecMismatch

An operation combined distinct decimal types.

Fields

left: DecimalSpec

The left operand type.

right: DecimalSpec

The right operand type.

LossyRescale

Reducing scale would discard nonzero decimal digits.

Fields

from_scale: u8

The source scale.

to_scale: u8

The requested scale.

Trait Implementations

impl Clone for DecimalError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DecimalError

impl Debug for DecimalError

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

Formats the value using the given formatter.

impl Display for DecimalError

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

Formats the value using the given formatter.

impl Eq for DecimalError

impl Error for DecimalError

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 From<DecimalError> for MoneyError

fn from(error: DecimalError) -> Self

Converts to this type from the input type.

impl PartialEq for DecimalError

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

Equality operator ==.

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

Inequality operator !=.
