Struct MapSegment 

pub struct MapSegment {
    pub id: (usize, usize),
    pub point1: [f32; 2],
    pub point2: [f32; 2],
}

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

Mirrors sde::objects::SdeSegment’s shape (id, point1, point2) so callers that already hold sde connection data can build one with a straight field-for-field copy; the only structural difference is f32 instead of f64 for the coordinates, matching egui’s own coordinate type (egui — and therefore this widget — doesn’t work in f64).

Lines are installed with Map::add_hashmap_lines, keyed by an id that nodes reference through MapPoint::connections. The bounding box the R-tree uses for broad-phase viewport culling and hit-testing is computed on demand from point1/point2 in envelope rather than cached on the struct, same as SdeSegment.

Fields

id: (usize, usize)

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

point1: [f32; 2]

One endpoint of the segment, in map coordinates.

point2: [f32; 2]

The other endpoint of the segment, in map coordinates.

Implementations

impl MapSegment

pub fn new(id: (usize, usize), point1: [f32; 2], point2: [f32; 2]) -> Self

Creates a segment for id between point1 and point2.

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 Copy for MapSegment

impl Debug for MapSegment

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

Formats the value using the given formatter.

impl PartialEq for MapSegment

fn eq(&self, other: &MapSegment) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl RTreeObject for MapSegment

type Envelope = AABB<[f32; 2]>

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.
