Enum Closure 

pub enum Closure {
    Open,
    Closed,
}

Whether a ring repeats its first point as its last.

Mirrors boost::geometry::closure_selector from boost/geometry/core/closure.hpp.

Examples

use geometry_trait::Closure;
assert_ne!(Closure::Open, Closure::Closed);

Variants

Open

Last point != first point — algorithms close the ring on the fly.

Mirrors boost::geometry::open (value 0) from boost/geometry/core/closure.hpp.

Closed

Last point == first point — the ring carries the closing vertex explicitly.

Mirrors boost::geometry::closed (value 1) from boost/geometry/core/closure.hpp. This is the Boost default (traits::closure<G>::value = closed), and the default returned by crate::Ring::closure.
