Struct CaptionFontStyle

pub struct CaptionFontStyle {
    pub family: Option<CaptionFontFamily>,
    pub color: Option<ColorRgba>,
    pub relative_size: Option<f32>,
    pub char_edge_style: Option<EdgeStyle>,
    /* private fields */
}

Font, size, and color of closed captions text.

Fields

family: Option<CaptionFontFamily>

color: Option<ColorRgba>

47 CFR §79.103(c)(2) requires at least 3-bit RGB for user override of closed-captions color.

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

relative_size: Option<f32>

Size of closed captions text relative to the default captions size. A range of [0.5, 2] is guaranteed to be supported (as 47 CFR §79.103(c)(4) establishes). Size should be a finite number.

char_edge_style: Option<EdgeStyle>

Trait Implementations

impl Clone for CaptionFontStyle

fn clone(&self) -> CaptionFontStyle

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CaptionFontStyle

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

Formats the value using the given formatter.

impl<D: ResourceDialect> Decode<CaptionFontStyle, D> for CaptionFontStyle

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<'_, D>, offset: usize, depth: Depth, ) -> Result<()>

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

impl Default for CaptionFontStyle

fn default() -> CaptionFontStyle

Returns the “default value” for a type.

impl<D: ResourceDialect> Encode<CaptionFontStyle, D> for &CaptionFontStyle

unsafe fn encode( self, encoder: &mut Encoder<'_, D>, 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 for CaptionFontStyle

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl TypeMarker for CaptionFontStyle

type Owned = CaptionFontStyle

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 CaptionFontStyle

type Borrowed<'a> = &'a CaptionFontStyle

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(value: &<Self as TypeMarker>::Owned) -> Self::Borrowed<'_>

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