What keeps someone out.

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.

Unnamed

A control with no name: a screen reader says only what it is.

Fields

role: Role

What it is.

bounds: Rect

Where it is.

RepeatedId

Two nodes with the same id, which assistive technology takes for one.

Fields

id: u64

The id.

FocusOnNothing

Keyboard focus is on a node the tree does not have.

FocusStuck

Tab does not move the focus.

Fields

on: Option<String>

What it stays on.

FocusTrapped

Tab goes round some of the controls and never reaches the others.

Fields

reached: usize

How many it reaches.

of: usize

How many there are.

missed: Option<String>

The first one it never reaches.

LowContrast

Two colors of a theme are too close to read one on the other.

Fields

theme: String

The theme.

pair: String

The color in front and the one behind, by their tokens.

ratio: f32

Their contrast.

least: f32

The least it should be.

WindowHeld

A window over the screen that Escape does not close, so the keyboard cannot leave it.

Fields

name: Option<String>

What the window is called.

SharedShortcut

More than one command answers to the same keys.

Fields

keys: String

The keys, as they are written next to a command.

times: usize

How many commands.
