Struct MapSegment 

pub struct MapSegment {
    pub id: Rc<str>,
    pub raw_line: RawLine,
    pub aabb: AABB<RawPoint>,
}

A connection line between two points on the map, ready to be stored in an rstar::RTree.

MapSegment is the line object of the widget: it carries the segment geometry (RawLine) plus its precomputed axis-aligned bounding box (AABB), which the R-tree uses as the spatial envelope for broad-phase viewport culling and hit-testing. Lines are installed with Map::add_lines, keyed by an id that nodes reference through MapPoint::connections.

Fields

id: Rc<str>

Identifier shared with the line key (and with the MapPoint::connections of the endpoint nodes).

raw_line: RawLine

The segment geometry, in map coordinates.

aabb: AABB<RawPoint>

Axis-aligned bounding box of the segment, in map coordinates.

Implementations

impl MapSegment

pub fn new(id: Rc<str>, point1: RawPoint, point2: RawPoint) -> Self

Creates a segment for id from point1 to point2, computing its bounding box.

Trait Implementations

impl Clone for MapSegment

fn clone(&self) -> MapSegment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MapSegment

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

Formats the value using the given formatter.

impl RTreeObject for MapSegment

type Envelope = AABB<RawPoint>

The object’s envelope type. Usually, AABB will be the right choice. This type also defines the object’s dimensionality.

fn envelope(&self) -> Self::Envelope

Returns the object’s envelope.
