Struct Polyline 

pub struct Polyline {
    pub points: Vec<Point>,
    pub bulges: Vec<f64>,
    pub closed: bool,
}

Open or closed polyline whose segments may be circular arcs (DXF-style bulge).

Fields

points: Vec<Point>

Vertices.

bulges: Vec<f64>

Bulge per segment (tan(sweep/4)); empty means all straight.

closed: bool

Whether the last vertex connects back to the first.

Implementations

impl Polyline

pub fn open(points: Vec<Point>) -> Self

Straight open polyline.

pub fn closed(points: Vec<Point>) -> Self

Straight closed polyline.

pub fn segment_count(&self) -> usize

Number of segments.

pub fn bulge(&self, i: usize) -> f64

Bulge of segment i (0 when absent).

pub fn has_arcs(&self) -> bool

Whether any segment is an arc.

pub fn segment(&self, i: usize) -> Option<Curve>

Segment i as a curve.

Trait Implementations

impl Clone for Polyline

fn clone(&self) -> Polyline

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Polyline

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Polyline

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Polyline

fn eq(&self, other: &Polyline) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Polyline

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
