Enum GeneralError

pub enum GeneralError<T> {
    NegOverflow(T),
    PosOverflow(T),
    Unrepresentable(T),
}

A general error enumeration that subsumes all other conversion errors.

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

Variants

NegOverflow(T)

Input was too negative for the target type.

PosOverflow(T)

Input was too positive for the target type.

Unrepresentable(T)

Input was not representable in the target type.

Implementations

impl<T> GeneralError<T>

pub fn into_inner(self) -> T

Returns the value stored in this error.

Trait Implementations

impl<T: Clone> Clone for GeneralError<T>

fn clone(&self) -> GeneralError<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for GeneralError<T>

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

Formats the value using the given formatter.

impl<T> Error for GeneralError<T>

where T: Any,

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

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

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

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 GeneralError<T>

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

Converts to this type from the input type.

impl<T> From<NoError> for GeneralError<T>

fn from(_: NoError) -> Self

Converts to this type from the input type.

impl<T> From<PosOverflow<T>> for GeneralError<T>

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

impl<T: Ord> Ord for GeneralError<T>

fn cmp(&self, other: &GeneralError<T>) -> 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<T: PartialEq> PartialEq for GeneralError<T>

fn eq(&self, other: &GeneralError<T>) -> 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<T: PartialOrd> PartialOrd for GeneralError<T>

fn partial_cmp(&self, other: &GeneralError<T>) -> 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.

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.
