Struct fidl_fuchsia_ui_gfx::DirectionalLightArgs

#[repr(C)]
pub struct DirectionalLightArgs {
    pub dummy: u32,
}

A DirectionalLight is a Light that is emitted from a point at infinity.

Although the light is directional, the light has some amount of angular dispersion (i.e., the light is not fully columnated). For simplicity, we assume the dispersion of the light source is symmetric about the light’s primary direction.

Supported commands:

• SetLightColor
• SetLightDirection

Fields

dummy: u32

impl Clone for DirectionalLightArgs

fn clone(&self) -> DirectionalLightArgs

Returns a copy of the value.

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

impl Debug for DirectionalLightArgs

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

Formats the value using the given formatter.

impl Decode<DirectionalLightArgs> for DirectionalLightArgs

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<DirectionalLightArgs> for &DirectionalLightArgs

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<T0: Encode<u32>> Encode<DirectionalLightArgs> for (T0,)

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 FromBytes for DirectionalLightArgswhere u32: FromBytes,

fn read_from<B>(bytes: B) -> Option<Self>where B: ByteSlice, Self: Sized,

Reads a copy of Self from bytes.

fn read_from_prefix<B>(bytes: B) -> Option<Self>where B: ByteSlice, Self: Sized,

Reads a copy of Self from the prefix of bytes.

fn read_from_suffix<B>(bytes: B) -> Option<Self>where B: ByteSlice, Self: Sized,

Reads a copy of Self from the suffix of bytes.

fn new_zeroed() -> Selfwhere Self: Sized,

Creates an instance of Self from zeroed bytes.

impl Hash for DirectionalLightArgs

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 DirectionalLightArgs

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<DirectionalLightArgs> for DirectionalLightArgs

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

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl TypeMarker for DirectionalLightArgs

type Owned = DirectionalLightArgs

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 DirectionalLightArgs

type Borrowed<'a> = &'a <DirectionalLightArgs 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.
