Struct Vertex 

pub struct Vertex {}

A vertex, defined in global (3D) coordinates

This struct exists to distinguish between vertices and points at the type level. This is a relevant distinction, as vertices are part of a shape that help define its topology.

Points, on the other hand, might be used to approximate a shape for various purposes, without presenting any deeper truth about the shape’s structure.

Validation

Vertices must be unique within a shape, meaning an identical vertex must not exist in the same shape. In the context of vertex uniqueness, points that are close to each other are considered identical. The minimum distance between distinct vertices can be configured using the respective field in ValidationConfig.

Equality

Vertex contains no data and exists purely to be used within a Handle, where Handle::id can be used to compare different instances of Vertex.

If Vertex had Eq/PartialEq implementations, it containing no data would mean that all instances of Vertex would be considered equal. This would be very error-prone.

If you need to reference a Vertex from a struct that needs to derive Eq/Ord/…, you can use HandleWrapper<Vertex> to do that. It will use Handle::id to provide those Eq/Ord/… implementations.
