Trait Implementations

impl<V: Clone + Debug + Display> Clone for VariantError<V>

fn clone(&self) -> VariantError<V>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<V: Debug + Debug + Display> Debug for VariantError<V>

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

Formats the value using the given formatter.

impl<V: Debug + Display> Display for VariantError<V>

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

Formats the value using the given formatter.

impl<V: Debug + Display> Error for VariantError<V>

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<V: Debug + Display> From<VariantError<V>> for String

fn from(err: VariantError<V>) -> Self

Converts to this type from the input type.

impl<V: PartialEq + Debug + Display> PartialEq for VariantError<V>

fn eq(&self, other: &VariantError<V>) -> 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.
