Enum OperationalError

#[non_exhaustive]
pub enum OperationalError {
    Arithmetic,
    System,
}

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.

Arithmetic

System

Implementations

impl OperationalError

pub const fn is_arithmetic(&self) -> bool

Returns true if the enum is OperationalError::Arithmetic otherwise false

pub const fn is_system(&self) -> bool

Returns true if the enum is OperationalError::System otherwise false

Trait Implementations

impl AsRef<str> for OperationalError

fn as_ref(&self) -> &str

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

impl Clone for OperationalError

fn clone(&self) -> OperationalError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OperationalError

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

Formats the value using the given formatter.

impl Display for OperationalError

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

Formats the value using the given formatter.

impl EnumCount for OperationalError

const COUNT: usize = 2usize

impl From<OperationalError> for Errors

fn from(kind: OperationalError) -> Self

Converts to this type from the input type.

impl Hash for OperationalError

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 Ord for OperationalError

fn cmp(&self, other: &OperationalError) -> 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 PartialEq for OperationalError

fn eq(&self, other: &OperationalError) -> 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 PartialOrd for OperationalError

fn partial_cmp(&self, other: &OperationalError) -> 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.

impl VariantNames for OperationalError

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

Names of the variants of this enum
