Enum RationalError 

pub enum RationalError {
    ZeroDenominator,
    DivisionByZero,
    NormalizationOverflow,
    ArithmeticOverflow {
        operation: &'static str,
    },
}

Errors returned by validated rational-number helpers.

Variants

ZeroDenominator

A rational denominator must not be zero.

DivisionByZero

Division by a zero-valued rational is undefined.

NormalizationOverflow

Sign normalization could not be represented in the current integer type.

ArithmeticOverflow

Exact arithmetic overflowed the current integer representation.

Fields

operation: &'static str

The checked operation that overflowed.

Trait Implementations

impl Clone for RationalError

fn clone(&self) -> RationalError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RationalError

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

Formats the value using the given formatter.

impl Display for RationalError

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

Formats the value using the given formatter.

impl Error for RationalError

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 RationalError

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