Enum SurfaceExtent 

pub enum SurfaceExtent {
    Fixed(u32),
    Content,
}

Per-axis sizing for layer surfaces.

Fixed is a size in logical pixels (plain integers convert into it). Content follows the content’s natural size on that axis — the content() constructor reads like fill() and friends:

SurfaceConfig::new()
    .width(360)             // fixed
    .height(content());     // follows the toast stack

Content semantics, designed to stay footgun-free:

• Resizing is asynchronous (one compositor round trip per change) and happens on CONTENT changes, not per animation frame: the natural size is measured against animation targets, so an animated growth resizes once up front and the animation plays inside the final-size surface.
• On an axis anchored to both screen edges the compositor owns the size; Content there is ignored with a warning at creation.
• An exclusive zone of ExclusiveZone::Auto follows content resizes; every other policy never moves.

Variants

Fixed(u32)

Fixed size in logical pixels.

Content

Follow the content’s natural size on this axis.
