Struct TypefaceInfo

pub struct TypefaceInfo {
    pub asset_id: Option<u32>,
    pub font_index: Option<u32>,
    pub family: Option<FamilyName>,
    pub style: Option<Style2>,
    pub languages: Option<Vec<LocaleId>>,
    pub generic_family: Option<GenericFontFamily>,
    /* private fields */
}

Collection of typeface metadata that should be sufficient for clients to perform some kind of selection (likely via human) and request an exact font.

Fields

asset_id: Option<u32>

Identifier for the font asset. This ID is valid for the lifetime of the font service. May be used in conjunction with font_index to directly request this font.

font_index: Option<u32>

Index of the font within its parent asset. May be used in conjunction with asset_id to directly request this font.

family: Option<FamilyName>

style: Option<Style2>

languages: Option<Vec<LocaleId>>

generic_family: Option<GenericFontFamily>

Trait Implementations

impl Clone for TypefaceInfo

fn clone(&self) -> TypefaceInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TypefaceInfo

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

Formats the value using the given formatter.

impl<D> Decode<TypefaceInfo, D> for TypefaceInfo

where D: ResourceDialect,

fn new_empty() -> TypefaceInfo

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<(), Error>

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

impl Default for TypefaceInfo

fn default() -> TypefaceInfo

Returns the “default value” for a type.

impl<D> Encode<TypefaceInfo, D> for &TypefaceInfo

where D: ResourceDialect,

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

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

impl PartialEq for TypefaceInfo

fn eq(&self, other: &TypefaceInfo) -> 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 TypefaceInfo

type Owned = TypefaceInfo

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 TypefaceInfo

type Borrowed<'a> = &'a TypefaceInfo

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: &<TypefaceInfo as TypeMarker>::Owned, ) -> <TypefaceInfo as ValueTypeMarker>::Borrowed<'_>

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