Converts to this type from the input type.

impl From<StateChangeSuccess> for StateChangeReturn

fn from(value: StateChangeSuccess) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for StateChangeReturn

type Checker = GenericValueTypeChecker<StateChangeReturn>

Value type checker.

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

Get the contained value from a Value.

impl HasParamSpec for StateChangeReturn

type ParamSpec = ParamSpecEnum

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for StateChangeReturn

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 StateChangeReturn

fn cmp(&self, other: &StateChangeReturn) -> 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 + PartialOrd,

impl PartialEq for StateChangeReturn

fn eq(&self, other: &StateChangeReturn) -> 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.

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.
