Struct abi_stable::nonexhaustive_enum::UnwrapEnumError

#[non_exhaustive]
#[repr(transparent)]
pub struct UnwrapEnumError<N> {
    pub non_exhaustive: N,
}

An error for a situation where a NonExhaustive<> could not be unwrapped into the enum because the discriminant wasn’t valid in this context (likely because it is from a newer version of the library).

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

non_exhaustive: N

This field is either a NonExhaustive<> or a DiscrAndEnumInfo<>

Implementations

impl<N> UnwrapEnumError<N>

pub fn into_inner(self) -> N

Gets the non_exhaustive field.

pub fn into_boxed(self) -> RBoxError

where N: NonExhaustiveSharedOps,

Converts this into a boxed error.

Trait Implementations

impl<N: Clone> Clone for UnwrapEnumError<N>

fn clone(&self) -> UnwrapEnumError<N>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<N> Debug for UnwrapEnumError<N>

where N: NonExhaustiveSharedOps,

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

Formats the value using the given formatter.

impl<N> Display for UnwrapEnumError<N>

where N: NonExhaustiveSharedOps,

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

Formats the value using the given formatter.

impl<N> Error for UnwrapEnumError<N>

where N: NonExhaustiveSharedOps,

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

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<N> From<UnwrapEnumError<N>> for RBoxError

where N: NonExhaustiveSharedOps,

fn from(uee: UnwrapEnumError<N>) -> RBoxError

Converts to this type from the input type.

impl<N> GetStaticEquivalent_ for UnwrapEnumError<N>

where N: __StableAbi,

type StaticEquivalent = _static_UnwrapEnumError<<N as GetStaticEquivalent_>::StaticEquivalent>

The 'static equivalent of Self

impl<N: Ord> Ord for UnwrapEnumError<N>

fn cmp(&self, other: &UnwrapEnumError<N>) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl<N: PartialEq> PartialEq for UnwrapEnumError<N>

fn eq(&self, other: &UnwrapEnumError<N>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

where N: __StableAbi,

type IsNonZeroType = <N as StableAbi>::IsNonZeroType

Whether this type has a single invalid bit-pattern.

const LAYOUT: &'static TypeLayout = _
