A trait implemented by types upon which can be drawn.

Required methods

fn receive_draw(
    &mut self,
    ctx: &mut Context,
    texture: &Texture,
    position: (i32, i32),
    config: &DrawConfig
) -> Result<(), ErrDontCare>

Draws the texture onto self.

fn receive_clear_color(
    &mut self,
    ctx: &mut Context,
    color: (f32, f32, f32, f32)
) -> Result<(), ErrDontCare>

Sets each pixel of self to color.

fn receive_line(
    &mut self,
    ctx: &mut Context,
    from: (i32, i32),
    to: (i32, i32),
    color: (f32, f32, f32, f32)
) -> Result<(), ErrDontCare>

Draws a line from from to to.

The pixel at to is not part of the line.

Implementors

impl DrawTarget for Texture[src]

fn receive_draw(
    &mut self,
    ctx: &mut Context,
    texture: &Texture,
    position: (i32, i32),
    config: &DrawConfig
) -> Result<(), ErrDontCare>[src]

Draws the texture onto self. This permanently alters self, in case the original is still required, consider cloning this Texture first.

It is recommended to call Context::draw instead of using this method directly.

impl DrawTarget for WindowSurface[src]

fn receive_draw(
    &mut self,
    ctx: &mut Context,
    texture: &Texture,
    position: (i32, i32),
    config: &DrawConfig
) -> Result<(), ErrDontCare>[src]

Draws texture to the window, to finish the frame, call Context::finalize_frame.
