Enum GeneralErrorKind

pub enum GeneralErrorKind {
    NegOverflow,
    PosOverflow,
    Unrepresentable,
}

A general error enumeration that subsumes all other conversion errors, but discards all input payloads the errors may be carrying.

This exists primarily as a “catch-all” for reliably unifying various different kinds of conversion errors, and between different input types.

Variants

NegOverflow

Input was too negative for the target type.

PosOverflow

Input was too positive for the target type.

Unrepresentable

Input was not representable in the target type.

Trait Implementations

impl Clone for GeneralErrorKind

fn clone(&self) -> GeneralErrorKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GeneralErrorKind

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

Formats the value using the given formatter.

impl Display for GeneralErrorKind

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

Formats the value using the given formatter.

impl Error for GeneralErrorKind

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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<T> From<FloatError<T>> for GeneralErrorKind

fn from(e: FloatError<T>) -> GeneralErrorKind

Converts to this type from the input type.

impl<T> From<GeneralError<T>> for GeneralErrorKind

fn from(e: GeneralError<T>) -> Self

Converts to this type from the input type.

impl<T> From<NegOverflow<T>> for GeneralErrorKind

fn from(_: NegOverflow<T>) -> Self

Converts to this type from the input type.

impl From<NoError> for GeneralErrorKind

fn from(_: NoError) -> Self

Converts to this type from the input type.

impl<T> From<PosOverflow<T>> for GeneralErrorKind

fn from(_: PosOverflow<T>) -> Self

Converts to this type from the input type.

impl<T> From<RangeError<T>> for GeneralErrorKind

fn from(e: RangeError<T>) -> Self

Converts to this type from the input type.

impl From<RangeErrorKind> for GeneralErrorKind

fn from(e: RangeErrorKind) -> Self

Converts to this type from the input type.

impl<T> From<Unrepresentable<T>> for GeneralErrorKind

fn from(_: Unrepresentable<T>) -> Self

Converts to this type from the input type.

impl Ord for GeneralErrorKind

fn cmp(&self, other: &GeneralErrorKind) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for GeneralErrorKind

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

impl PartialOrd for GeneralErrorKind

fn partial_cmp(&self, other: &GeneralErrorKind) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
