Enum TooltipBorder 

#[non_exhaustive]
pub enum TooltipBorder {
    Sides,
    Full,
    None,
}

Border chrome vocabulary for Tooltip.

Each backend can ask for a particular border style: side bars only, a full 4-sided box, or no border at all. An optional title can be embedded in the top border row when the border is Full.

#[non_exhaustive]: marking it means a future variant (e.g. a Rounded corner style) is additive instead of a breaking change.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Sides

Vertical bars on the left/right edge only — no top or bottom rule, regardless of box height. title is not rendered in this mode.

Full

A closed box on all four sides. The default: all backends stroke a full rectangle here when there is room; on TUI, if the box is too short (height < 3 or width < 2), the border falls back to Sides chrome so the tooltip still shows border.

Carries title, centred into the top border row, when set.

None

No border chrome at all — background fill (and text) only. title is not rendered in this mode.
