Struct gfx_graphics::GfxGraphics

pub struct GfxGraphics<'a, R, C> where R: Resources + 'a, C: CommandBuffer<R> + 'a, R::Buffer: 'a, R::Shader: 'a, R::Program: 'a, R::Texture: 'a, R::Sampler: 'a {
    pub encoder: &'a mut Encoder<R, C>,
    // some fields omitted
}

Used for rendering 2D graphics.

Fields

encoder: &'a mut Encoder<R, C>

Provide access to the gfx::Encoder in case a user needs to update textures for caching, etc.
