Enum ConversionError 

#[non_exhaustive]
pub enum ConversionError {
    OutOfRange {
        value: String,
        target: &'static str,
    },
    NotFinite {
        value: f64,
    },
}

Error returned when a Number cannot be converted into a fixed-size numeric type because the value falls outside that type’s representable range.

This was Eq in 0.2.0 and is not any more: ConversionError::NotFinite carries an f64, which is not Eq, and no manual implementation could honestly supply one. PartialEq is unchanged, so == still works — only an Eq bound stops compiling. The loss is declared in the README’s migration table, which is where the 0.3.0 CHANGELOG is written from.

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.

OutOfRange

The value does not fit in the requested target type.

Fields

value: String

The offending value, rendered as a decimal string.

target: &'static str

The name of the target type that could not hold the value.

NotFinite

The value is NaN or infinite, which has no rational representation.

Fields

value: f64

The offending value.

Trait Implementations

impl Clone for ConversionError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConversionError

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

Formats the value using the given formatter.

impl Display for ConversionError

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

Formats the value using the given formatter.

impl Error for ConversionError

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 ConversionError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
