Struct Chain 

pub struct Chain {
    pub segments: Vec<Segment>,
    pub closed: bool,
}

An open or closed directed curve (edge chains, trace paths).

Fields

segments: Vec<Segment>

closed: bool

Implementations

impl Chain

pub fn open(segments: Vec<Segment>) -> Self

pub fn from_loop(l: &Loop) -> Self

pub fn length(&self) -> f64

pub fn start(&self) -> Option<Point2>

pub fn end(&self) -> Option<Point2>

pub fn reversed(&self) -> Self

pub fn discretize(&self, tol: f64) -> Vec<Point2>

Chord points along the chain; a closed chain repeats its first point last.

pub fn validate(&mut self, tol: &Tolerance) -> Result<(), PlanarError>

Trait Implementations
