Struct Layout 

struct Layout {
    thickness: i32,
    min_height: i32,
    x_height: i32,
    padding: i32,
}

Layout measurements used by StackNavigationBar to compute bar sizes and spacing.

This small value object caches DPI- and font-dependent sizing parameters that are computed once and reused across layout and resizing logic:

• thickness: thickness of the separator between bars (scaled by DPI)
• min_height: minimum allowed height for a bar (usually SMALL_BAR_HEIGHT - thickness)
• x_height: font x-height used to compute line heights
• padding: extra vertical padding inside a bar (derived from min_height and x_height)

Keeping these values together makes it easier to reason about sizing and to pass a consistent set of layout metrics into functions that need them.

Fields

thickness: i32

Thickness of the separators between bars (in pixels).

min_height: i32

Minimum height of a bar (in pixels).

x_height: i32

Font x-height used to compute per-line heights (in pixels).

padding: i32

Vertical padding used inside bars (in pixels).
