Enum AccessibleLiveness

#[non_exhaustive]
#[repr(u32)]pub enum AccessibleLiveness {
    Off = 0,
    Polite = 1,
    Assertive = 2,
}

Expand description

This enum represents the different values of the accessible-live-region property. It indicates that an element is a live region whose content changes should be announced by assistive technologies.

Variants (Non-exhaustive)§

This enum is marked as 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.

Off = 0

Use in regions that present information that is of low-importance to the user. Assistive technologies are expected to not announce changes unless the user explicitly asks for it.

Polite = 1

Use in regions that present new information to users. Assistive technologies are expected to not interrupt the user to inform of changes to the live region.

Assertive = 2

Use in regions that present information that a user should know about right away. Assistive technologies are expected to announce to the user as soon as possible.
