A Node

Required Methods§

source

fn lat_lon(&self) -> Option<(Lat, Lon)>

Latitude & Longitude of the node (if it’s set)

source

fn set_lat_lon_direct(&mut self, loc: Option<(Lat, Lon)>)

Directly set the lat & lon of the node, see set_lat_lon() as a more convienient method.

Provided Methods§

source

fn lat_lon_f64(&self) -> Option<(f64, f64)>

Latitude & Longitude of the node as f64 (if it’s set)

source

fn has_lat_lon(&self) -> bool

True iff this node has latitude & longitude set

source

fn unset_lat_lon(&mut self)

Remove the lat & lon for this node

source

fn set_lat_lon<LL, L1, L2>(&mut self, loc: LL) -> Result<(), ParseLatLonError>where L1: TryInto<Lat>, L2: TryInto<Lon>, LL: Into<Option<(L1, L2)>>, ParseLatLonError: From<<L1 as TryInto<Lat>>::Error> + From<<L2 as TryInto<Lon>>::Error>,

Set the Latitude & Longitude.

The type signature is complicated so you can convert from f64

use osmio::Node;

// It can convert from f64
node.set_lat_lon((0.0_f64, 0.0_f64));
assert_eq!(node.lat_lon_f64().unwrap(), (0., 0.));

// .. or from f32
node.set_lat_lon((0.0_f32, 0.0_f32));
assert_eq!(node.lat_lon_f64().unwrap(), (0., 0.));

// You can set to None too
node.set_lat_lon(None as Option<(f64, f64)>);
assert!(node.lat_lon_f64().is_none());
