}

The ratio string is invalid and cannot be parsed.

Variants

DivisionByZero

The ratio string is divided by zero.

MultipleSlashes

The ratio string contains multiple slashes.

For example, “1/2/3”.

NonNumericCharactersInFractions

The ratio string contains non-numeric characters in fractions.

For example, “1/2A”.

MultipleScientificNotations

The ratio string contains multiple scientific notations.

For example, “1.5E6E6”.

MultipleDecimalPoints

The ratio string contains multiple decimal points.

For example, “1.5.6”.

ExponentPartIsNotAnInteger

The exponent part of the ratio string is not an integer.

For example, “1.5E6.5”.

ParsingBigIntError(ParseBigIntError)

The ratio string is deficient in some other way.

Trait Implementations

impl Debug for RatioFromStrError

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

Formats the value using the given formatter.

impl Display for RatioFromStrError

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

Formats the value using the given formatter.

impl Error for RatioFromStrError

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 RatioFromStrError

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