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.

fn clone(&self) -> CachePolicy

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CachePolicy

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

Formats the value using the given formatter.

impl From<CachePolicy> for Value

fn from(v: CachePolicy) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for CachePolicy

type Checker = GenericValueTypeChecker<CachePolicy>

Value type checker.

unsafe fn from_value(value: &'a Value) -> Self

Get the contained value from a Value.

impl HasParamSpec for CachePolicy

type ParamSpec = ParamSpecEnum

type SetValue = CachePolicy

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str, _: CachePolicy) -> ParamSpecEnumBuilder<'_, CachePolicy>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for CachePolicy

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 CachePolicy

fn cmp(&self, other: &CachePolicy) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<CachePolicy> for CachePolicy

fn eq(&self, other: &CachePolicy) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<CachePolicy> for CachePolicy

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for CachePolicy

fn to_value(&self) -> Value

Convert a value to a Value.

fn value_type(&self) -> Type

Returns the type identifier of self.

impl ValueType for CachePolicy

type Type = CachePolicy

Type to get the Type from.
