Struct RenderBackend 

pub struct RenderBackend {
    pub name: &'static str,
    pub priority: i32,
    pub renderer: fn() -> Box<dyn Renderer>,
}

One render backend: its name, its rank under auto, and how to make its renderer.

Fields

name: &'static str

The name an app’s configuration selects it by.

priority: i32

Trial order when the configuration names no backend: higher first.

renderer: fn() -> Box<dyn Renderer>

A renderer bound to nothing yet. Construction does no work; binding to a window or an offscreen image happens in Renderer::attach, and a failure there is what lets a launch try the next backend.
