Trait TryFromWkt

pub trait TryFromWkt<T>: Sized {
    type Error;

    // Required methods
    fn try_from_wkt_str(wkt_str: &str) -> Result<Self, Self::Error>;
    fn try_from_wkt_reader(wkt_reader: impl Read) -> Result<Self, Self::Error>;
}

Create geometries from WKT.

A default implementation exists for geo-types, or you can implement this trait for your own types.

Required Associated Types

type Error

Required Methods

fn try_from_wkt_str(wkt_str: &str) -> Result<Self, Self::Error>

Examples

// This example requires the geo-types feature (on by default).
use wkt::TryFromWkt;
use geo_types::Point;
let point: Point<f64> = Point::try_from_wkt_str("POINT(10 20)").unwrap();
assert_eq!(point.y(), 20.0);

fn try_from_wkt_reader(wkt_reader: impl Read) -> Result<Self, Self::Error>

Examples

// This example requires the geo-types feature (on by default).
use wkt::TryFromWkt;
use geo_types::Point;

let fake_file = "POINT(10 20)".as_bytes().to_vec();
let point: Point<f64> = Point::try_from_wkt_reader(&*fake_file).unwrap();
assert_eq!(point.y(), 20.0);

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
