Trait geo::algorithm::convert::TryConvert

pub trait TryConvert<T, U> {
    type Output;

    fn try_convert(&self) -> Self::Output;
}

Convert (fallibly) the type of a geometry’s coordinate value.

Examples

use geo::{TryConvert, LineString, line_string};

let line_string_64: LineString<i64> = line_string![
    (x: 5, y: 10),
    (x: 3, y: 1),
    (x: 8, y: 9),
];

let line_string_32: Result<LineString<i32>, _> = line_string_64.try_convert();
