Struct TypefaceRequest 

pub struct TypefaceRequest {
    pub query: Option<TypefaceQuery>,
    pub flags: Option<TypefaceRequestFlags>,
    pub cache_miss_policy: Option<CacheMissPolicy>,
    /* private fields */
}

Parameters for requesting a typeface.

Fields

query: Option<TypefaceQuery>

Parameters for looking up a typeface.

flags: Option<TypefaceRequestFlags>

Flags for how to process the request, such as which kinds of substitutions are permitted.

cache_miss_policy: Option<CacheMissPolicy>

Setting for what to do if the requested typeface exists but is not cached, and therefore cannot be served immediately.

If this field is empty, the default policy is [fuchsia.fonts/CacheMissPolicy.BLOCK_UNTIL_DOWNLOADED].

If the client needs an immediate response, it can choose one of the non-blocking policies. In this case, clients can also register to be notified when new fonts have been added to the cache by calling [fuchsia.fonts/Provider.RegisterFontSetEventListener].

Trait Implementations

impl Clone for TypefaceRequest

fn clone(&self) -> TypefaceRequest

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TypefaceRequest

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

Formats the value using the given formatter.

impl<D> Decode<TypefaceRequest, D> for TypefaceRequest

where D: ResourceDialect,

fn new_empty() -> TypefaceRequest

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 TypefaceRequest

fn default() -> TypefaceRequest

Returns the “default value” for a type.

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

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 TypefaceRequest

fn eq(&self, other: &TypefaceRequest) -> 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 Persistable for TypefaceRequest

impl StructuralPartialEq for TypefaceRequest

impl TypeMarker for TypefaceRequest

type Owned = TypefaceRequest

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 TypefaceRequest

type Borrowed<'a> = &'a TypefaceRequest

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

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