Struct Polyline 

Source 
pub struct Polyline(/* private fields */);
Expand description

A Polyline is a sequence of connected Points. It’s considered closed if the first and last points are the same.

Polyline is the data structure used by FlattenedPath.

It can be constructed with a vector of Points, or from an iterator of Point-compatible items.
