Supported accessibility settings.

Fields

audio_description: Option<bool>

For videos, use an alternative audio track (akin to changing languages) that explains what is happening visually while there is no dialogue.

screen_reader: Option<bool>

Read aloud elements of the screen selected by the user.

color_inversion: Option<bool>

Invert colors on the screen.

enable_magnification: Option<bool>

Interpret triple-tap on the touchscreen as a command to zoom in.

color_correction: Option<ColorBlindnessType>

What type of color-blindness, if any, to correct for.

captions_settings: Option<CaptionsSettings>

What kind of sources get closed captions, and how they look.

Implementations

impl AccessibilitySettings

pub const EMPTY: Self = _

An empty table with every field set to None.

Trait Implementations

impl Clone for AccessibilitySettings

fn clone(&self) -> AccessibilitySettings

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AccessibilitySettings

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

Formats the value using the given formatter.

impl Decodable for AccessibilitySettings

fn new_empty() -> Self

Creates a new value of this type with an “empty” representation.

fn decode(&mut self, decoder: &mut Decoder<'_>, offset: usize) -> Result<()>

Decodes an object of this type from the decoder’s buffers into self. Callers must ensure that offset is a multiple of Layout::inline_align, and that decoder.buf has room for reading Layout::inline_size bytes at offset.

impl Encodable for AccessibilitySettings

fn encode( &mut self, encoder: &mut Encoder<'_, '_>, offset: usize, recursion_depth: usize ) -> Result<()>

Encode the object into the buffer. Any handles stored in the object are swapped for Handle::INVALID. Callers must ensure that offset is a multiple of Layout::inline_align, and that encoder.buf has room for writing Layout::inline_size bytes at offset.

impl Layout for AccessibilitySettings

fn inline_align(_context: &Context) -> usize

Returns the minimum required alignment of the inline portion of the encoded object. It must be a (nonzero) power of two.

fn inline_size(_context: &Context) -> usize

Returns the size of the inline portion of the encoded object, including padding for the type’s alignment. Must be a multiple of inline_align.

fn supports_simple_copy() -> boolwhere Self: Sized,

Returns true iff the type can be encoded or decoded via simple copy.

impl PartialEq<AccessibilitySettings> for AccessibilitySettings

fn eq(&self, other: &AccessibilitySettings) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
