Struct ConversionProperties

pub struct ConversionProperties {
    pub coefficients: Option<[f32; 9]>,
    pub preoffsets: Option<[f32; 3]>,
    pub postoffsets: Option<[f32; 3]>,
    /* private fields */
}

The properties required to apply color conversion to the display. The conversion is applied to each pixel of the display according to the formula:

[coefficients * (pixel + preoffsets) + postoffsets].

where pixel is a column vector consisting of the pixel’s 3 RGB components.

Fields

coefficients: Option<[f32; 9]>

The |coefficients| param represents a 3x3 matrix, where the values are given in row-major order:

| 0 1 2 | | 3 4 5 | | 6 7 8 |

preoffsets: Option<[f32; 3]>

Preoffsets and postoffsets represent a [3x1] vector each of RGB values.

postoffsets: Option<[f32; 3]>

Trait Implementations

impl Clone for ConversionProperties

fn clone(&self) -> ConversionProperties

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ConversionProperties

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

Formats the value using the given formatter.

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

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 Default for ConversionProperties

fn default() -> ConversionProperties

Returns the “default value” for a type.

impl<D: ResourceDialect> Encode<ConversionProperties, D> for &ConversionProperties

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 ConversionProperties

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

type Owned = ConversionProperties

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 ConversionProperties

type Borrowed<'a> = &'a ConversionProperties

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.
