Enum zng::event::CommandScope

pub enum CommandScope {
    App,
    Window(WindowId),
    Widget(WidgetId),
}

Represents the scope of a Command.

The command scope defines the targets of its event and the context of its metadata.

Variants

App

Default scope, this is the scope of command types declared using command!.

Window(WindowId)

Scope of a window.

Note that the window scope is different from the window root widget scope, the metadata store and command handles are different, but subscribers set on the window root should probably also subscribe to the window scope.

Widget(WidgetId)

Scope of a widget.

Trait Implementations

fn from(id: WidgetId) -> CommandScope

Converts to this type from the input type.

impl From<WindowId> for CommandScope

fn from(id: WindowId) -> CommandScope

Converts to this type from the input type.

impl Hash for CommandScope

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 IntoVar<CommandScope> for &'static str

fn into_var(self) -> <&'static str as IntoVar<CommandScope>>::Var

Widget scope.

type Var = LocalVar<CommandScope>

Variable type that will wrap the T value.

fn into_boxed_var(self) -> Box<dyn VarBoxed<T>>

where Self: Sized,

Converts into BoxedVar<T>.

impl IntoVar<CommandScope> for Txt

fn into_var(self) -> <Txt as IntoVar<CommandScope>>::Var

Widget scope.

type Var = LocalVar<CommandScope>

Variable type that will wrap the T value.

fn into_boxed_var(self) -> Box<dyn VarBoxed<T>>

where Self: Sized,

Converts into BoxedVar<T>.

impl IntoVar<CommandScope> for WidgetId

type Var = LocalVar<CommandScope>

Variable type that will wrap the T value.

fn into_var(self) -> <WidgetId as IntoVar<CommandScope>>::Var

Converts the source value into a var.

fn into_boxed_var(self) -> Box<dyn VarBoxed<T>>

where Self: Sized,

Converts into BoxedVar<T>.

impl IntoVar<CommandScope> for WindowId

type Var = LocalVar<CommandScope>

Variable type that will wrap the T value.

fn into_var(self) -> <WindowId as IntoVar<CommandScope>>::Var

Converts the source value into a var.

fn into_boxed_var(self) -> Box<dyn VarBoxed<T>>

where Self: Sized,

impl PartialEq for CommandScope

fn eq(&self, other: &CommandScope) -> 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 Serialize for CommandScope

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
