Enum Depth 

pub enum Depth {
    Flat,
    Raised,
    Well,
}

How a region sits relative to the surface behind it.

Fill and bevel are named together because naming them apart is what let them disagree. Every consumer measured had at least one region carrying a raised bevel over a recessed fill: audiofiles fixed it in raised_frame and recorded the bug in its doc comment, and Balanced Breakfast still had twelve of them a year later. A single name for the pair makes that unrepresentable.

Variants

Flat

Level with its surroundings. No edge.

Raised

A card laid on the panel it sits in.

Well

A hole in the panel, with content down inside it. For anything the user looks into: a table body, a tag tree, a text field.

Implementations

impl Depth

pub const fn bevel(self) -> Option<Bevel>

The edge this depth is drawn with, if it has one.

pub const fn fill(self) -> Option<Fill>

The surface this depth is filled with.

Depth::Flat has no fill of its own: it inherits whatever it sits on, which is the difference between level-with and painted-the-same-colour.

pub const fn pressed(self) -> Self

Pressing a raised region reads as a well, and nothing else moves.
