Convenient macro to build GraphicsPipelineInfo. Allows to skip fields when their default values are sufficient. The only required fields are:

• vertex_shader
• layout
• render_pass Note that default primitive_topology is TriangleList.

Example

graphics_pipeline_info! {
    vertex_shader: Shader::new(vertex_shader.clone()),
    layout: pipeline_layout.clone(),
    render_pass: render_pass.clone(),
    rasterizer: Rasterizer::simple(
        Shader::new(fragment_shader.clone()),
        false,
    ),
}
