Struct NodeHandle 

pub struct NodeHandle<'a> { /* private fields */ }

A borrowed node, obtained from Map::node, that an animation can be attached to.

Modifiers such as NodeHandle::color come first; the effect method is the terminal call that writes everything at once. A modifier on its own does nothing, so there is no way to configure a notification that does not exist.

Effects come in two families, and which one you call decides how it ends:

• pulse, ripple, countdown, scale_in and crosshair play once from the Instant you pass and stop on their own.
• halo, blink and orbit are lasting state: they run until clear, and keep the app repainting the whole time.

A node can carry one of each at once; the state is drawn underneath the event.

Implementations

impl NodeHandle<'_>

pub fn color(self, color: Color32) -> Self

Overrides the colour of the effect about to be attached.

Without this the effect uses the current style’s alert_color.

pub fn pulse(self, at: Instant)

Expanding, fading disc. Reads as “one thing happened here”.

pub fn ripple(self, at: Instant)

Three staggered expanding rings. Reads as “activity is ongoing”.

pub fn countdown(self, at: Instant)

A ring emptying clockwise. Reads as “how old is this information”.

pub fn scale_in(self, at: Instant)

A disc that overshoots and settles. For a node that just appeared.

pub fn crosshair(self, at: Instant)

Four ticks converging on the node. Reads as “target acquired”.

pub fn halo(self)

Lasting ring whose opacity breathes. Runs until Self::clear.

pub fn blink(self)

Lasting thick ring blinking on and off. Runs until Self::clear.

pub fn orbit(self)

Lasting dot circling the node. Runs until Self::clear.

pub fn clear(self)

Removes both the notification and the lasting state of this node.
