Enum ExternalError

#[non_exhaustive]
pub enum ExternalError<T = String> {
    Custom(T),
    Unknown,
}

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Custom(T)

Unknown

Implementations

impl<T> ExternalError<T>

pub const fn is_custom(&self) -> bool

Returns true if the enum is ExternalError::Custom otherwise false

pub const fn is_unknown(&self) -> bool

Returns true if the enum is ExternalError::Unknown otherwise false

impl<T> ExternalError<T>

pub fn custom(error: T) -> Self

pub fn unknown() -> Self

Trait Implementations

impl<T> AsRef<str> for ExternalError<T>

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl<T: Clone> Clone for ExternalError<T>

fn clone(&self) -> ExternalError<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for ExternalError<T>

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

Formats the value using the given formatter.

impl<T> Default for ExternalError<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T> Display for ExternalError<T>

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

Formats the value using the given formatter.

impl<T> EnumCount for ExternalError<T>

const COUNT: usize = 2usize

impl From<ExternalError> for Errors

fn from(kind: ExternalError) -> Self

Converts to this type from the input type.

impl<T: Hash> Hash for ExternalError<T>

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<T: Ord> Ord for ExternalError<T>

fn cmp(&self, other: &ExternalError<T>) -> 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<T: PartialEq> PartialEq for ExternalError<T>

fn eq(&self, other: &ExternalError<T>) -> 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<T: PartialOrd> PartialOrd for ExternalError<T>

fn partial_cmp(&self, other: &ExternalError<T>) -> 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.

const VARIANTS: &'static [&'static str]

Names of the variants of this enum
