Required Associated Types

type Path: Path

Required Methods

fn set_fill_type(&mut self, fill_type: FillType)

Sets the fill type.

fn move_to(&mut self, location: impl Into<PixelPoint>)

Move the cursor to the specified location.

fn line_to(&mut self, location: impl Into<PixelPoint>)

Add a line segment from the current cursor location to the given location. The cursor location is updated to be at the endpoint.

fn cubic_curve_to( &mut self, control_point_1: impl Into<PixelPoint>, control_point_2: impl Into<PixelPoint>, end_point: impl Into<PixelPoint>, )

Add a cubic bezier curve whose start point is current cursor location to the specified end point using the two specified control points. The cursor location is updated to be at the endpoint.

fn add_rounded_rect( &mut self, rect: impl Into<PixelRect>, rounding_radii: &RoundingRadii, )

Add a rounded rect with potentially non-uniform radii to the path.

fn add_oval(&mut self, oval_bounds: impl Into<PixelRect>)

Add an oval to the path.

fn add_arc( &mut self, oval_bounds: impl Into<PixelRect>, start_angle_degrees: f32, end_angle_degrees: f32, )

Add an arc to the path.

fn close(&mut self)

Close the path.

fn build(self) -> Self::Path

Builds the path.

fn build_copy(&mut self) -> Self::Path

Create a new path by copying the existing built-up path. The existing path can continue being added to.

Provided Methods

fn quadratic_curve_to( &mut self, control_point: impl Into<PixelPoint>, end_point: impl Into<PixelPoint>, )

Add a quadratic bezier curve from whose start point is the cursor to the specified end point using the a single control point. The cursor location is updated to be at the endpoint.

fn add_rect(&mut self, rect: impl Into<PixelRect>)

Adds a rectangle to the path.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
