Struct VertexDist 

pub struct VertexDist {
    pub x: f64,
    pub y: f64,
    pub dist: f64,
}

A vertex with coordinates and the distance to the next vertex. Port of C++ vertex_dist.

The calc_dist method computes the distance to another vertex_dist and returns true if the distance exceeds VERTEX_DIST_EPSILON (i.e., the vertices are not coincident).

Fields

x: f64

y: f64

dist: f64

Implementations

impl VertexDist

pub fn new(x: f64, y: f64) -> Self

pub fn calc_dist(&mut self, val: &VertexDist) -> bool

Calculate distance to val and store it. Returns true if the points are not coincident (distance > VERTEX_DIST_EPSILON). If coincident, sets dist to 1.0 / VERTEX_DIST_EPSILON.
