Trait Implementations

impl<E: Clone + Error> Clone for ValueTypeMismatchOrNoneError<E>

fn clone(&self) -> ValueTypeMismatchOrNoneError<E>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<E: Debug + Error> Debug for ValueTypeMismatchOrNoneError<E>

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

Formats the value using the given formatter.

impl<E: Error> Display for ValueTypeMismatchOrNoneError<E>

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

Formats the value using the given formatter.

impl<E: Error> Error for ValueTypeMismatchOrNoneError<E>

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, demand: &mut Demand<'a>)

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

Provides type based access to context intended for error reports.

impl<E: Error> From<E> for ValueTypeMismatchOrNoneError<E>

fn from(err: E) -> Self

Converts to this type from the input type.

impl<E: PartialEq + Error> PartialEq<ValueTypeMismatchOrNoneError<E>> for ValueTypeMismatchOrNoneError<E>

fn eq(&self, other: &ValueTypeMismatchOrNoneError<E>) -> 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.
