Struct SegmentHandle 

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

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

Mirrors NodeHandle, with the same modifier-then-terminal shape:

• flash, comet_once and wipe play once from the Instant you pass and stop on their own.
• comet, dash, glow_band and chevrons are lasting state: they run until clear, and keep the app repainting the whole time.

A segment can carry one of each at once; the state is drawn underneath the event, same as node effects.

Implementations

impl SegmentHandle<'_>

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 flash(self, at: Instant)

Brief flash that fades back out. The segment analogue of NodeHandle::pulse — reads as “something happened on this route”.

pub fn comet_once(self, at: Instant, direction: CometDirection)

Single dot pass from one endpoint to the other, then gone. The event-driven counterpart to Self::comet — reads as “one thing moved along this route just now” rather than “traffic keeps flowing this way”. direction picks which endpoint it starts from.

pub fn wipe(self, at: Instant)

Line drawing itself in from the first endpoint to the second, then gone — reads as “this route was just established” rather than “something travelled along it”.

pub fn comet(self)

Lasting dot travelling along the segment. Runs until Self::clear.

pub fn dash(self)

Lasting dashed line, its pattern sliding along the segment (“marching ants”). Runs until Self::clear.

pub fn glow_band(self)

Lasting band of brightness travelling the length of the segment and looping. Reads as “flow”, calmer than Self::dash. Runs until Self::clear.

pub fn chevrons(self)

Lasting row of arrow shapes sliding along the segment, pointing the way. Runs until Self::clear.

pub fn clear(self)

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