Enum OverlaySide 

pub enum OverlaySide {
    Top,
    Right,
    Bottom,
    Left,
}

The overlay-portal authoring surface: the slot a widget that floats its own surface holds, what that surface is anchored to, and the placement geometry every anchored pattern needs.

Promoted here rather than left to each design system because all three of them had derived the same geometry independently: a design system’s popover, menu, tooltip and context menu place a surface through place and host it through OverlaySlot, reaching both through frust::authoring alone. The side of the anchor a floated surface opens on.

The web vocabulary every anchored-overlay pattern in this workspace already speaks (Radix’s side, and the four-sided tooltip variants each catalog grew on top of it).

Variants

Top

Above the anchor.

Right

To the trailing side of the anchor.

Bottom

Below the anchor — the default.

Left

To the leading side of the anchor.
