Struct Action Copy item path

impl<Message> Action<Message>

pub fn capture() -> Action<Message>

Creates a new “capturing” Action. A capturing Action will make other widgets consider it final and prevent further processing.

Prevents “event bubbling”.

pub fn publish(message: Message) -> Action<Message>

Creates a new Action that publishes the given Message for the application to handle.

Publishing a Message always produces a redraw.

pub fn request_redraw() -> Action<Message>

Creates a new Action that requests a redraw to happen as soon as possible; without publishing any Message.

pub fn request_redraw_at(at: Instant) -> Action<Message>

Creates a new Action that requests a redraw to happen at the given Instant; without publishing any Message.

This can be useful to efficiently animate content, like a blinking caret on a text input.

pub fn and_capture(self) -> Action<Message>

Marks the Action as “capturing”. See Self::capture.

pub fn into_inner(self) -> (Option<Message>, RedrawRequest, Status)

Converts the Action into its internal parts.

This method is meant to be used by runtimes, libraries, or internal widget implementations.

impl<T> Downcast<T> for T

fn downcast(&self) -> &T

impl<T> Downcast for T
where T: Any,

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

impl<T> DowncastSync for T
where T: Any + Send + Sync,

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Send + Sync>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.

impl<T> From<T> for T

fn from(t: T) -> T

Returns the argument unchanged.

impl<T> Instrument for T

fn instrument(self, span: Span) -> Instrumented<Self>

fn in_current_span(self) -> Instrumented<Self>

Instruments this type with the current Span, returning an Instrumented wrapper. Read more

impl<T, U> Into for T
where U: From<T>,

fn into(self) -> U

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

fn into_boot(self) -> (State, Task<Message>)

Turns some type into the initial state of some Application.

impl<T> IntoEither for T

fn into_either(self, into_left: bool) -> Either<Self, Self>

fn into_either_with<F>(self, into_left: F) -> Either<Self, Self>
where F: FnOnce(&Self) -> bool,

Converts self into a Left variant of Either<Self, Self> if into_left(&self) returns true. Converts self into a Right variant of Either<Self, Self> otherwise. Read more
