Enum RestoreReason 

#[non_exhaustive]
pub enum RestoreReason {
    Pristine,
    Launch,
    Recover,
    Restore,
}

Available on crate feature v4_22 only.

Enumerates possible reasons for an application to restore saved state.

See restore-state.

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.

Pristine

Don’t restore anything

Launch

This is normal launch. Restore as little as is reasonable

Recover

The application has crashed before. Try to restore the previous state

Restore

This is a session restore. Restore the previous state as far as possible

Trait Implementations

impl Clone for RestoreReason

fn clone(&self) -> RestoreReason

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RestoreReason

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

Formats the value using the given formatter.

impl From<RestoreReason> for Value

fn from(v: RestoreReason) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for RestoreReason

type Checker = GenericValueTypeChecker<RestoreReason>

Value type checker.

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

Get the contained value from a Value.

impl HasParamSpec for RestoreReason

type ParamSpec = ParamSpecEnum

type SetValue = RestoreReason

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for RestoreReason

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 RestoreReason

fn cmp(&self, other: &RestoreReason) -> 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 RestoreReason

fn eq(&self, other: &RestoreReason) -> 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 RestoreReason

fn partial_cmp(&self, other: &RestoreReason) -> 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 StaticType for RestoreReason

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for RestoreReason

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 RestoreReason

type Type = RestoreReason

Type to get the Type from.

impl Copy for RestoreReason

impl Eq for RestoreReason

impl StructuralPartialEq for RestoreReason
