Struct Effect 

pub struct Effect<M> { /* private fields */ }

What Widget::update asks for: async work, plus requests to the host.

Implementations

impl<M> Effect<M>

pub fn none() -> Self

pub fn task(task: Task<M>) -> Self

pub fn and_task(self, task: Task<M>) -> Self

where M: Send + 'static,

Runs task too, alongside the one it has.

pub fn open_popover(self) -> Self

Opens this widget’s popover, under its item. Ignored if the widget has no popover. Before the item was ever clicked, it opens on the bar the notifications show on.

pub fn close_popover(self) -> Self

pub fn open_dialog(self) -> Self

Opens this widget’s dialog: its panel in the middle of the screen, for what needs more room than a popover. Ignored if the widget has no dialog.

The host picks where it comes from: out of what was just acted on (the popover, which folds away, the item, a notification or the dormer), or out of the top of the screen, and it goes back there when it closes. Opening it closes any popover and the dormer.

pub fn close_dialog(self) -> Self

pub fn nudge(self, nudge: Nudge) -> Self

Nudges this widget’s island. Ignored while the island is held or has a popover.

pub fn nudge_lasting(self, nudge: Nudge, lasting: Duration) -> Self

Nudges this widget’s island in step with something else on screen that takes lasting, like the compositor’s own workspace animation: the host plays the same motion, slowed down or sped up to settle over about that long.

Trait Implementations

impl<M> From<Task<M>> for Effect<M>

fn from(task: Task<M>) -> Self

Converts to this type from the input type.
