A rectangular set of pixels that can be drawn on with a Shader

Required Associated Types

type Uniforms

The type of uniform data that is supported by this shader

type CoordinateSpace: CoordinateSpace

The coordiante space over which this shader can operate

type Pixel

The format of the pixels produced by this shader

Required Methods

fn set_shader<T: Shader<Self::Uniforms, Self::CoordinateSpace, Self::Pixel> + 'static>( &mut self, shader: T, )

Sets the shader for this surface

fn clear_shader(&mut self)

Clears the shader

fn set_rect(&mut self, rect: Rectangle<Self::CoordinateSpace>)

Changes the size of the surface

fn set_opacity(&mut self, opacity: Fract8)

Sets the opacity of this surface, where 0 is completely transparent and 255 is completely opaque

fn set_visible(&mut self, visible: bool)

Sets the visibility of the surface without adjusting the stored opacity

fn set_offset(&mut self, offset: Coordinates<Self::CoordinateSpace>)

Sets the scroll offset of the surface without adjusting shader coordinates

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
