Struct AreaLayer 

pub struct AreaLayer {
    pub node_radius: f32,
    pub node_fill: Color32,
    pub mode: AreaMode,
    /* private fields */
}

Layer implementation that allows the user to draw polygons on the map.

Fields

node_radius: f32

The radius of the nodes.

node_fill: Color32

The fill color of the nodes.

mode: AreaMode

The current drawing mode.

Implementations

impl AreaLayer

pub fn new() -> Self

Creates a new AreaLayer.

pub fn add_area(&mut self, area: Area)

Adds a new area to the layer.

pub fn to_geojson_str(&self) -> Result<String, Error>

Serializes the layer to a GeoJSON FeatureCollection.

pub fn from_geojson_str(&mut self, s: &str) -> Result<(), Error>

Deserializes a GeoJSON FeatureCollection and adds the features to the layer.

Trait Implementations

impl Clone for AreaLayer

fn clone(&self) -> AreaLayer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for AreaLayer

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AreaLayer

where AreaLayer: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Layer for AreaLayer

fn as_any(&self) -> &dyn Any

Gets the layer as a dyn Any.

fn as_any_mut(&mut self) -> &mut dyn Any

Gets the layer as a mutable dyn Any.

fn handle_input( &mut self, response: &Response, projection: &MapProjection, ) -> bool

Handles user input for the layer. Returns true if the input was handled and should not be processed further by the map.

fn draw(&self, painter: &Painter, projection: &MapProjection)

Draws the layer.
