🚩+ A numeric-related error.

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.

NotImplemented

The requested numerical functionality is not implemented.

This is the default implementation of every numeric trait method.

NotSupported

The requested numerical functionality is not supported.

Unspecified

Unspecified error.

When no clearer error can be given.

Invalid

An invalid value was received for the given type or operation.

NoInverse

An inverse doesn’t exist.

MismatchedSizes

The provided values are not compatible in size.

IncompatibleBounds

The given bounds are not compatible.

NonNegativeRequired

A non-negative value is required.

PositiveRequired

A positive value is required.

NonZeroRequired

A non-zero value is required.

Overflow(Option<Sign>)

An arithmetic overflow error, with an optional associated sign.

Trait Implementations

impl Clone for NumError

fn clone(&self) -> NumError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NumError

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

Formats the value using the given formatter.

impl Display for NumError

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

Formats the value using the given formatter.

impl Error for NumError

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 ExtError for NumError

type Kind = ()

Represents the specific kind of error, if applicable.

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

Checks if two errors are equivalent based on their kind or other criteria.

fn error_kind(&self) -> Self::Kind

Returns the kind of the error, if applicable.

impl Hash for NumError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for NumError

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