The type of an accessibility node.

The majority of these roles come from the ARIA specification. Reference the latest draft for proper usage.

Like the AccessKit schema as a whole, this list is largely taken from Chromium. However, unlike Chromium’s alphabetized list, this list is ordered roughly by expected usage frequency (with the notable exception of Role::Unknown). This is more efficient in serialization formats where integers use a variable-length encoding.

Variants

Unknown = 0

InlineTextBox = 1

Cell = 2

StaticText = 3

Image = 4

Link = 5

Row = 6

ListItem = 7

ListMarker = 8

Contains the bullet, number, or other marker for a list item.

TreeItem = 9

ListBoxOption = 10

MenuItem = 11

MenuListOption = 12

Paragraph = 13

GenericContainer = 14

A generic container that should be ignored by assistive technologies and filtered out of platform accessibility trees. Equivalent to the ARIA none or presentation role, or to an HTML div with no role.

ListGrid = 187

Behaves similar to an ARIA grid but is primarily used by Chromium’s TableView and its subclasses, so they can be exposed correctly on certain platforms.

Terminal = 188

This is just like a multi-line document, but signals that assistive technologies should implement behavior specific to a VT-100-style terminal.

Implementations

impl Role

pub fn n(value: u8) -> Option<Role>

Trait Implementations

impl Clone for Role

fn clone(&self) -> Role

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Role

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for Role

fn default() -> Role

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Role

fn deserialize<__D>( __deserializer: __D ) -> Result<Role, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Role

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Role

fn cmp(&self, other: &Role) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Role
