pub trait Within<Other> {
// Required method
fn is_within(&self, b: &Other) -> bool;
}Expand description
Tests if a geometry is completely within another geometry.
In other words, the DE-9IM intersection matrix for (Self, Rhs) is [T*F**F***]
§Examples
use geo::{point, line_string};
use geo::algorithm::Within;
let line_string = line_string![(x: 0.0, y: 0.0), (x: 2.0, y: 4.0)];
assert!(point!(x: 1.0, y: 2.0).is_within(&line_string));
// Note that a geometry on only the *boundary* of another geometry is not considered to
// be _within_ that geometry. See [`Relate`] for more information.
assert!(! point!(x: 0.0, y: 0.0).is_within(&line_string));Within is equivalent to Contains with the arguments swapped.
use geo::{point, line_string};
use geo::algorithm::{Contains, Within};
let line_string = line_string![(x: 0.0, y: 0.0), (x: 2.0, y: 4.0)];
let point = point!(x: 1.0, y: 2.0);
// These two comparisons are completely equivalent
assert!(point.is_within(&line_string));
assert!(line_string.contains(&point));
