where B: Default,

pub fn begin(&mut self, at: Point2D<f32, UnknownUnit>) -> EndpointId

Starts a new sub-path at a given position.

There must be no sub-path in progress when this method is called. at becomes the current position of the sub-path.

pub fn end(&mut self, close: bool)

Ends the current sub path.

A sub-path must be in progress when this method is called. After this method is called, there is no sub-path in progress until begin is called again.

pub fn close(&mut self)

Closes the current sub path.

Shorthand for builder.end(true).

pub fn line_to(&mut self, to: Point2D<f32, UnknownUnit>) -> EndpointId

Adds a line segment to the current sub-path.

A sub-path must be in progress when this method is called.
