}

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

Fields

for_media: Option<bool>

Closed captions enabled for media sources of audio.

for_tts: Option<bool>

Closed captions enabled for Text-To-Speech sources of audio.

font_style: Option<CaptionFontStyle>

Font style and color used for the closed captions text.

window_color: Option<ColorRgba>

Border color used around the closed captions window.

Each color channel should be a finite number otherwise will cause SetAccessibilityInfo to fail with INVALID_VALUE.

background_color: Option<ColorRgba>

Background color of the closed captions window.

Each color channel should be a finite number otherwise will cause SetAccessibilityInfo to fail with INVALID_VALUE.

Implementations

impl CaptionsSettings

pub const EMPTY: Self = _

An empty table with every field set to None.

Trait Implementations

impl Clone for CaptionsSettings

fn clone(&self) -> CaptionsSettings

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CaptionsSettings

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

Formats the value using the given formatter.

impl Decode<CaptionsSettings> for CaptionsSettings

fn new_empty() -> Self

Creates a valid instance of Self. The specific value does not matter, since it will be overwritten by decode.

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

Decodes an object of type T from the decoder’s buffers into self.

impl Encode<CaptionsSettings> for &CaptionsSettings

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

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID.

impl Encode<CaptionsSettings> for CaptionsSettings

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

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID.

impl PartialEq<CaptionsSettings> for CaptionsSettings

fn eq(&self, other: &CaptionsSettings) -> 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.

impl TypeMarker for CaptionsSettings

type Owned = CaptionsSettings

The owned Rust type which this FIDL type decodes into.

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 alignment. Must be a multiple of inline_align.

fn encode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and encoding requires no validation. When true, we can optimize encoding arrays and vectors of Self::Owned to a single memcpy.

fn decode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and decoding requires no validation. When true, we can optimize decoding arrays and vectors of Self::Owned to a single memcpy.

impl ValueTypeMarker for CaptionsSettings

type Borrowed<'a> = &'a <CaptionsSettings as TypeMarker>::Owned

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &Self::Owned. There are three cases:

fn borrow<'a>(value: &'a <Self as TypeMarker>::Owned) -> Self::Borrowed<'a>

Cheaply converts from &Self::Owned to Self::Borrowed.
