Enum LightValue

pub enum LightValue {
    On(bool),
    Brightness(f64),
    Color(ColorRgb),
}

Value of a light. Only one of the three values in the union will be present, depending on the light’s LightType.

Variants

On(bool)

Lights with LightType.SIMPLE will have this value.

Brightness(f64)

Lights with LightType.BRIGHTNESS will have this value, a floating point value 0.0 to 1.0 inclusive, where 0.0 means the light is off. Not a number (NaN), infinity or negative infinity will cause SetLightGroup to fail with INVALID_VALUE.

Color(ColorRgb)

Lights with LightType.RGB will have this value.

Each color channel should be a value between 0.0 and 1.0 inclusive. Values outside this range will cause SetLightGroup to fail with INVALID_VALUE.

Implementations

impl LightValue

pub fn ordinal(&self) -> u64

pub fn is_unknown(&self) -> bool

👎Deprecated: Strict unions should not use is_unknown

Trait Implementations

impl Clone for LightValue

fn clone(&self) -> LightValue

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LightValue

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

Formats the value using the given formatter.

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

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<LightValue, D> for &LightValue

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 LightValue

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

type Owned = LightValue

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 LightValue

type Borrowed<'a> = &'a LightValue

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.
