Enum ParseRatioErr 

#[non_exhaustive]
pub enum ParseRatioErr {
    Empty,
    Overflow,
    Numerator(ParseIntError),
    Denominator(ParseIntError),
}

An error which can be returned when parsing a ratio.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Empty

Value being parsed is empty.

Among other causes, this variant will be constructed when parsing an empty string.

Overflow

Numbers are too large to store together in the fraction field.

Numerator(ParseIntError)

Error when parsing numerator.

Denominator(ParseIntError)

Error when parsing denominator.

This will contain an error kind of Zero if the denominator is 0.

Trait Implementations

impl Clone for ParseRatioErr

fn clone(&self) -> ParseRatioErr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParseRatioErr

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

Formats the value using the given formatter.

impl Display for ParseRatioErr

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

Formats the value using the given formatter.

impl Error for ParseRatioErr

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 ParseRatioErr

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