fn register_enum() -> Type

Registers the enum only once.

Trait Implementations

impl Clone for CameraViewfinderState

fn clone(&self) -> CameraViewfinderState

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CameraViewfinderState

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

Formats the value using the given formatter.

impl Default for CameraViewfinderState

fn default() -> CameraViewfinderState

Returns the “default value” for a type.

impl From<CameraViewfinderState> for Value

fn from(v: CameraViewfinderState) -> Self

Converts to this type from the input type.

impl From<ViewfinderState> for CameraViewfinderState

fn from(value: ViewfinderState) -> Self

Converts to this type from the input type.

impl FromGlib<i32> for CameraViewfinderState

unsafe fn from_glib(value: i32) -> Self

impl<'a> FromValue<'a> for CameraViewfinderState

type Checker = GenericValueTypeChecker<CameraViewfinderState>

Value type checker.

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

Get the contained value from a Value.

impl HasParamSpec for CameraViewfinderState

type ParamSpec = ParamSpecEnum

type SetValue = CameraViewfinderState

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

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

fn param_spec_builder() -> Self::BuilderFn

impl IntoGlib for CameraViewfinderState

type GlibType = i32

fn into_glib(self) -> i32

impl PartialEq for CameraViewfinderState

fn eq(&self, other: &CameraViewfinderState) -> 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 static_type() -> Type

Returns the type identifier of Self.

impl ToValue for CameraViewfinderState

fn to_value(&self) -> Value

Convert a value to a Value.

fn value_type(&self) -> Type

Returns the type identifier of self.

impl TryFromGlib<i32> for CameraViewfinderState

type Error = i32

unsafe fn try_from_glib(value: i32) -> Result<Self, i32>

impl ValueType for CameraViewfinderState

type Type = CameraViewfinderState

Type to get the Type from.
