Struct MapPoint 

pub struct MapPoint {
    pub raw_point: RawPoint,
    pub connections: Vec<String>,
    /* private fields */
}

A node on the map: an id, a position and an optional display name.

Nodes are loaded into the widget through Map::add_hashmap_points, keyed by their id.

Fields

raw_point: RawPoint

Position of the node, in map coordinates.

connections: Vec<String>

Ids of the lines connecting this node with others.

Each entry must match a key of the map passed to Map::add_lines. The usual pattern is to push the same line id into the connections of both endpoint nodes. Line visibility is computed from the segment bounding boxes (R-tree), not from node visibility, so a line is drawn whenever its bounding box intersects the viewport.

Implementations

impl MapPoint

pub fn new(id: usize, coords: RawPoint) -> MapPoint

Creates a node with the given id at the given map coordinates.

pub fn get_id(&self) -> usize

Returns the node identifier.

pub fn get_name(&self) -> String

Returns the node display name (empty if it was never set).

pub fn set_name(&mut self, value: String)

Sets the node display name.
