Implementations

source

impl URLManager

source

pub fn update_url_free_param(free_param: String)

Modify the current URL to change the first free parameter in the HTTP GET params to the specified value, adding it if needed.

source

pub fn update_url_param(key: String, value: String)

Modify the current URL to change the first named parameter in the HTTP GET params to the specified value, adding it if needed.

source

pub fn get_cam_param(ctx: &EventCtx<'_>, gps_bounds: &GPSBounds) -> String

Get an OSM-style zoom/lat/lon string (https://wiki.openstreetmap.org/wiki/Browsing#Other_URL_tricks) based on the current viewport.

source

pub fn update_url_cam(ctx: &EventCtx<'_>, gps_bounds: &GPSBounds)

Modify the current URL to set –cam to an OSM-style zoom/lat/lon string (https://wiki.openstreetmap.org/wiki/Browsing#Other_URL_tricks) based on the current viewport.

source

pub fn change_camera(
 ctx: &mut EventCtx<'_>,
 raw: Option<&String>,
 gps_bounds: &GPSBounds
) -> bool

Parse an OSM-style zoom/lat/lon string (https://wiki.openstreetmap.org/wiki/Browsing#Other_URL_tricks), changing the canvas appropriately. Returns true upon success.

source

fn parse_center_camera(raw: &str, gps_bounds: &GPSBounds) -> Option<(Pt2D, f64 )>

Parse an OSM-style zoom/lat/lon string (https://wiki.openstreetmap.org/wiki/Browsing#Other_URL_tricks), returning the map point to center on and the camera zoom.

impl<T> Downcast for T where
T: Any,

fn into_any(self: Box<T, Global>) -> Box<dyn Any + 'static, Global>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait. Read more

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any + 'static>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait. Read more

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s. Read more

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s. Read more

impl<T> DowncastSync for T where
T: Any + Send + Sync,

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send + 'static>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait. Read more
