Trait Implementations

impl<E> Clone for ErrorKind<E>

where E: Clone,

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

Returns a copy of the value.

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

Performs copy-assignment from source.

Formats the value using the given formatter.

impl<E> Default for ErrorKind<E>

fn default() -> ErrorKind<E>

Return ErrorKind::External(Default::default())

impl<'de, E> Deserialize<'de> for ErrorKind<E>

where E: Deserialize<'de>,

fn deserialize<__D>( __deserializer: __D, ) -> Result<ErrorKind<E>, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<E> Error for ErrorKind<E>

where E: Debug,

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

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.

fn from(val: &'_enum ErrorKind<E>) -> ErrorKindDiscriminants

Converts to this type from the input type.

impl<E> From<ErrorKind<E>> for ErrorKindDiscriminants

fn from(val: ErrorKind<E>) -> ErrorKindDiscriminants

Converts to this type from the input type.

impl<K> From<ErrorKind<K>> for Error<K>

fn from(kind: ErrorKind<K>) -> Error<K>

Converts to this type from the input type.

impl<E> Hash for ErrorKind<E>

where E: Hash,

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

impl<E> IntoEnumIterator for ErrorKind<E>

type Iterator = ErrorKindIter<E>

fn iter() -> ErrorKindIter<E>

impl<E> Ord for ErrorKind<E>

where E: Ord,

fn cmp(&self, other: &ErrorKind<E>) -> 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.

where E: PartialEq,

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