Enum DecimalError

pub enum DecimalError {
    PrecLimitExceeded,
    MaxValueExceeded,
    InfiniteValue,
    NotANumber,
    DivisionByZero,
}

An error which can be returned from converting numbers to Decimal or from binary operators on Decimal.

This error is used as the error type for the TryFrom implementation of Decimal<P>. It is also used when the implementations of the numerical operators panic.

Variants

PrecLimitExceeded

The precise result would have more than crate::MAX_PREC fractional decimal digits.

MaxValueExceeded

The result would exceed the maximum value representable by the type.

InfiniteValue

Attempt to convert an infinite value to Decimal.

NotANumber

Attempt to convert a ‘not-a-number’ value to a Decimal.

DivisionByZero

A division op called with a divisor equal to zero.

Trait Implementations

impl Clone for DecimalError

fn clone(&self) -> DecimalError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

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 PartialEq for DecimalError

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