Fields

family: Option<String>

Desired font family name, e.g. “Roboto”. Font family search is case-insensitive. In case when there is no specified family or the specified family doesn’t have glyph for the requested character then a font from another family may be returned. This behavior can be disabled using REQUEST_FLAG_NO_FALLBACK.

weight: u32

For example, 400 is normal, 700 is bold.

width: u32

Numeric values matching OS/2 & Windows Metrics usWidthClass table. https://www.microsoft.com/typography/otspec/os2.htm For example, 5 is normal.

slant: Slant

language: Option<Vec<String>>

BCP47 language tags in order of preference. See https://tools.ietf.org/html/bcp47 .

character: u32

Codepoint for the character that must be present in the returned font or 0. Caller that specify this field are expected to extract character set from the result and cache it in order to avoid calling the API more than necessary.

fallback_group: FallbackGroup

Fallback group preference. Caller can leave this field set to NONE. In that case the font provider will use fallback group of the specified font family.

flags: u32

Trait Implementations

impl Clone for Request

fn clone(&self) -> Request

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Request

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

Formats the value using the given formatter.

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

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<D: ResourceDialect> Encode<Request, D> for &Request

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<D: ResourceDialect, T0: Encode<Optional<BoundedString<128>>, D>, T1: Encode<u32, D>, T2: Encode<u32, D>, T3: Encode<Slant, D>, T4: Encode<Optional<Vector<BoundedString<35>, 8>>, D>, T5: Encode<u32, D>, T6: Encode<FallbackGroup, D>, T7: Encode<u32, D>> Encode<Request, D> for (T0, T1, T2, T3, T4, T5, T6, T7)

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 Hash for Request

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Request

fn cmp(&self, other: &Request) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Request

fn eq(&self, other: &Request) -> 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 PartialOrd for Request

fn partial_cmp(&self, other: &Request) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl TypeMarker for Request

type Owned = Request

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 Request

type Borrowed<'a> = &'a Request

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.
