Struct LoweringInput 

pub struct LoweringInput {
    pub display: DisplayParams,
    pub format: SourceFormat,
    pub binding: BindingModel,
    pub fb_id: u32,
    pub crtc_id: u32,
    pub default_zpos: Option<u64>,
}

Everything lower_layer needs about a layer, without borrowing the scene.

Fields

display: DisplayParams

How to display the buffer.

format: SourceFormat

What the buffer is.

binding: BindingModel

Who owns the FB_ID write.

fb_id: u32

The framebuffer this frame, ignored for a driver-owned binding.

crtc_id: u32

The CRTC this scene drives.

default_zpos: Option<u64>

A stacking position to use when the caller set none.

The scene itself passes None; with this and the layer’s own zpos both unset, zpos is not written.
