Struct RouteGeometry 

pub struct RouteGeometry {
    pub edges: IdMap<EdgeId, RouteEdge>,
    pub start_pos: GridPoint,
    pub end_pos: GridPoint,
}

Fields

edges: IdMap<EdgeId, RouteEdge>

start_pos: GridPoint

end_pos: GridPoint

Implementations

impl RouteGeometry

pub fn edge(&self, edge_index: EdgeId) -> Option<&RouteEdge>

pub fn iter_edges(&self) -> impl Iterator<Item = (EdgeId, &RouteEdge)>

pub fn start_pos(&self) -> Pos2

pub fn end_pos(&self) -> Pos2

pub fn points(&self) -> Vec<Pos2>

The polyline’s corner sequence: the resolved start, then each edge’s end (no duplicated interior points).

pub fn hovered_corner(&self, hover_pos: Pos2) -> Option<(EdgeId, EdgeId)>

pub fn hovered_edge(&self, hover_pos: Pos2) -> Option<EdgeId>

pub fn hovered_edge_distance(&self, hover_pos: Pos2) -> Option<f32>

Perpendicular distance from hover_pos to the nearest point on the route, or None if the point isn’t within the hit radius (or sits on a terminal endpoint, which is left to the pin under it). Unlike hovered_edge this keeps interior corners hoverable. Lets a caller pick the closest route among several in range.

pub fn map_linear_distance_to_position( &self, linear_distance: FracVal, ) -> LocAndDirection

pub fn slide_along(&self, from: FracVal, delta: Vec2) -> FracVal

Slide an arc-length position along the route by a screen-space delta: map to world, offset, re-project onto the nearest point of the wire.

pub fn distance_along(&self, pos: Pos2) -> FracVal

The arc length along the route of the nearest point to pos.

Trait Implementations

impl Clone for RouteGeometry

fn clone(&self) -> RouteGeometry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RouteGeometry

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

Formats the value using the given formatter.

impl Default for RouteGeometry

fn default() -> RouteGeometry

Returns the “default value” for a type.

impl PartialEq for RouteGeometry

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
