Enum 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

impl Clone for CommandScope

fn clone(&self) -> CommandScope

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CommandScope

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CommandScope

fn deserialize<__D>( __deserializer: __D, ) -> Result<CommandScope, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&'static str> for CommandScope

fn from(widget_name: &'static str) -> CommandScope

Widget scope.

impl From<Txt> for CommandScope

fn from(widget_name: Txt) -> CommandScope

Widget scope.

impl From<WidgetId> for CommandScope

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) -> Var<CommandScope>

Widget scope.

impl IntoVar<CommandScope> for Txt

fn into_var(self) -> Var<CommandScope>

Widget scope.

impl IntoVar<CommandScope> for WidgetId

fn into_var(self) -> Var<CommandScope>

impl IntoVar<CommandScope> for WindowId

fn into_var(self) -> Var<CommandScope>

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.
