Trait DefaultPerimeter 

pub trait DefaultPerimeter<Family> {
    type Strategy: Default;
}

“Which perimeter strategy do we pick by default for this CS family?”

Mirrors the default-strategy resolution used by boost::geometry::perimeter in algorithms/perimeter.hpp:115-159.

Required Associated Types

type Strategy: Default

The perimeter strategy chosen for this family.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
