Trait Implementations

impl<K: Clone> Clone for Error<K>

fn clone(&self) -> Error<K>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<K: Debug> Debug for Error<K>

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

Formats the value using the given formatter.

impl<K: Default> Default for Error<K>

fn default() -> Error<K>

Returns the “default value” for a type.

impl<'de, K> Deserialize<'de> for Error<K>

where K: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<K> Display for Error<K>

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<E> From<&str> for Error<E>

fn from(err: &str) -> Self

Converts to this type from the input type.

impl<E> From<Box<dyn Error>> for Error<E>

fn from(err: Box<dyn Error>) -> Self

Converts to this type from the input type.

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

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

Converts to this type from the input type.

impl<E> From<String> for Error<E>

fn from(err: String) -> Self

Converts to this type from the input type.

impl<K, T> From<TryLockError<T>> for Error<K>

fn from(err: TryLockError<T>) -> Self

Converts to this type from the input type.

impl<K: Hash> Hash for Error<K>

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

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<K: Ord> Ord for Error<K>

fn cmp(&self, other: &Error<K>) -> 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,

Restrict a value to a certain interval.

impl<K: PartialEq> PartialEq for Error<K>

fn eq(&self, other: &Error<K>) -> 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<K: PartialOrd> PartialOrd for Error<K>

fn partial_cmp(&self, other: &Error<K>) -> Option<Ordering>

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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