Struct InvalidVariant

pub struct InvalidVariant;

An error type indicating that a FromStr call failed because the value was not a valid variant.

Trait Implementations

impl Clone for InvalidVariant

fn clone(&self) -> InvalidVariant

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for InvalidVariant

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

Formats the value using the given formatter.

impl Display for InvalidVariant

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

Formats the value using the given formatter.

impl Eq for InvalidVariant

#[doc(hidden)] fn assert_receiver_is_total_eq(&self)

impl Error for InvalidVariant

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

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

#[doc(hidden)] fn type_id(&self, _: Internal) -> TypeId

where Self: 'static,

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

Gets the TypeId of self.

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 From<InvalidVariant> for Error

fn from(err: InvalidVariant) -> Self

Converts to this type from the input type.

impl PartialEq for InvalidVariant

fn eq(&self, other: &InvalidVariant) -> 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 TryFrom<Error> for InvalidVariant

type Error = DifferentVariant

The type returned in the event of a conversion error.

fn try_from(err: Error) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for InvalidVariant

impl StructuralPartialEq for InvalidVariant
