Struct SurfaceRef 

pub struct SurfaceRef {
    pub fb_id: u32,
    pub width: u32,
    pub height: u32,
    pub x: i32,
    pub y: i32,
    pub generation: u64,
}

A decoration surface and where it goes.

Fields

fb_id: u32

The framebuffer to scan out, or zero for nothing.

width: u32

Width in pixels.

height: u32

Height in pixels.

x: i32

Destination x.

y: i32

Destination y.

generation: u64

The surface’s content generation, for damage tracking.

Implementations

impl SurfaceRef

pub const fn is_armed(self) -> bool

Whether this reference names anything to draw.

A zero framebuffer or a zero dimension is nothing, not an error: a caller with fewer windows than slots passes these, and a caller mid- resize passes them briefly.
