Struct Chain 

pub struct Chain {
    pub pieces: Vec<Piece>,
    pub joints: Vec<String>,
    pub smooth: Vec<bool>,
    pub closed: bool,
}

A chain of pieces, each starting where the one before ends — closed if the last ends where the first starts — and the names of its joints: joints[i] where piece i starts, and for an open chain one more, its end.

Fields

pieces: Vec<Piece>

joints: Vec<String>

smooth: Vec<bool>

Per piece, whether the chain is known to run on smoothly into it from the piece before — as the faces of a solid say, where a traced piece’s tangent only encloses its direction. Where not, its pieces’ tangents decide.

closed: bool

Implementations

impl Chain

pub fn offset(&self, distance: Scalar) -> GeopResult<Vec<NurbCurve2D>>

The chain moved distance to its left — negative: to its right — see the module docs.

pub fn band(&self, near: Scalar, far: Scalar) -> GeopResult<Vec<Profile>>

The band between the chain moved near and far to its left (near < far; zero for the chain itself) as the loops of a region, the outer one first and counter-clockwise, named after the pieces and joints: X and P for the near side, X,far and P,far for the far one, first and last the ends of an open chain.

Trait Implementations

impl Clone for Chain

fn clone(&self) -> Chain

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Chain

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

Formats the value using the given formatter.
