Enum fpdec::DecimalError

pub enum DecimalError {
    FracDigitLimitExceeded,
    InternalOverflow,
    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. It is also used when the implementations of the numerical operators panic.

Variants

FracDigitLimitExceeded

The precise result would have more than MAX_N_FRAC_DIGITS fractional decimal digits.

InternalOverflow

The result would exceed the internal representation of Decimal.

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 copy 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)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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
