I'm trying to use spatial-join crate (I see it's not updated for 2 years, but whatever). Simple code from an example doesn't work.
In the docs, struct Config has method serial:
pub fn serial<T, U>(self, small: T) -> Result<SpatialIndex, Error> where
T: TryInto<SplitGeoSeq, Error = U>,
U: Any,
and SplitGeoSeq has trait impl:
impl TryFrom<Vec<Point<f64>>> for SplitGeoSeq
So, my test code is this:
# [dependencies]
# geo = "0.23"
# spatial-join = "0.1"
use geo::geometry::Point;
use spatial_join::Config;
use std::error::Error;
fn main() -> Result<(), Box<dyn Error>> {
let mut stops_points = Vec::<Point<f64>>::new();
stops_points.push(Point::new(76.9, 43.2));
stops_points.push(Point::new(92.9, 56.0));
stops_points.push(Point::new(104.3, 52.3));
let idx = Config::new().serial(stops_points)?;
Ok(())
}
And the error says Vec<Point<f64>> must implement From, not TryFrom.
I'm puzzled, what's wrong? Actually, crate's own example doesn't compile in my rustc 1.61, with the same message:
|
13 | let idx = Config::new().serial(stops_points)?;
| ^^^^^^ the trait `From<Vec<geo::Point>>` is not implemented for `SplitGeoSeq`
