Enum Error 

pub enum Error<K, V> {
    Key(K),
    Value(V),
}

Possible errors when decoding a map entry.

Variants

Key(K)

Error decoding the key.

Value(V)

Error decoding the value.

Implementations

impl<K, V> Error<K, V>

pub fn map<KO, VO>( self, fk: impl FnOnce(K) -> KO, fv: impl FnOnce(V) -> VO, ) -> Error<KO, VO>

Map a function on the key and value errors.

Trait Implementations

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

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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

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

Formats the value using the given formatter.

impl<K: Display, V: Display> Display for Error<K, V>

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

Formats the value using the given formatter.

impl<K, V> Error for Error<K, V>

where K: Error + 'static, V: Error + 'static,

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<K: Hash, V: Hash> Hash for Error<K, V>

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: PartialEq, V: PartialEq> PartialEq for Error<K, V>

fn eq(&self, other: &Error<K, 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.
