Macro geo_types::wkt

macro_rules! wkt {
    ($($wkt:tt)+) => { ... };
}

Creates a crate::geometry from a WKT literal.

This is evaluated at compile time, so you don’t need to worry about runtime errors from invalid WKT syntax.

Note that POINT EMPTY is not accepted because it is not representable as a geo_types::Point.

use geo_types::wkt;
let point = wkt! { POINT(1.0 2.0) };
assert_eq!(point.x(), 1.0);
assert_eq!(point.y(), 2.0);

let geometry_collection = wkt! {
    GEOMETRYCOLLECTION(
        POINT(1.0 2.0),
        LINESTRING EMPTY,
        POLYGON((0.0 0.0,1.0 0.0,1.0 1.0,0.0 0.0))
    )
};
assert_eq!(geometry_collection.len(), 3);
