Struct style::values::RGBA

pub struct RGBA {
    pub red: u8,
    pub green: u8,
    pub blue: u8,
    pub alpha: u8,
}

A color with red, green, blue, and alpha components, in a byte each.

Fields

red: u8

The red component.

green: u8

The green component.

blue: u8

The blue component.

alpha: u8

The alpha component.

Implementations

impl RGBA

pub fn from_floats(red: f32, green: f32, blue: f32, alpha: f32) -> RGBA

Constructs a new RGBA value from float components. It expects the red, green, blue and alpha channels in that order, and all values will be clamped to the 0.0 … 1.0 range.

pub fn transparent() -> RGBA

Returns a transparent color.

pub fn new(red: u8, green: u8, blue: u8, alpha: u8) -> RGBA

Same thing, but with u8 values instead of floats in the 0 to 1 range.

pub fn red_f32(&self) -> f32

Returns the red channel in a floating point number form, from 0 to 1.

pub fn green_f32(&self) -> f32

Returns the green channel in a floating point number form, from 0 to 1.

pub fn blue_f32(&self) -> f32

Returns the blue channel in a floating point number form, from 0 to 1.

pub fn alpha_f32(&self) -> f32

Returns the alpha channel in a floating point number form, from 0 to 1.

Trait Implementations

impl Clone for RGBA

fn clone(&self) -> RGBA

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RGBA

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RGBA

fn deserialize<D>(
    deserializer: D
) -> Result<RGBA, <D as Deserializer<'de>>::Error>where
    D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<RGBA> for Color

fn from(value: RGBA) -> Self

Converts to this type from the input type.

impl MallocSizeOf for RGBA

fn size_of(&self, _: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl PartialEq<RGBA> for RGBA

fn eq(&self, other: &RGBA) -> 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 Serialize for RGBA

fn serialize<S>(
    &self,
    serializer: S
) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>where
    S: Serializer,

Serialize this value into the given Serde serializer.

impl ToAnimatedValue for RGBA

type AnimatedValue = RGBA

The type of the animated value.

fn to_animated_value(self) -> Self::AnimatedValue

Converts this value to an animated value.

fn from_animated_value(animated: Self::AnimatedValue) -> Self

Converts back an animated value into a computed value.

impl ToCss for RGBA

fn to_css<W>(&self, dest: &mut W) -> Result<(), Error>where
    W: Write,

Serialize self in CSS syntax, writing to dest.

fn to_css_string(&self) -> String

Serialize self in CSS syntax and return a string.

impl<'a> ToCss for RGBA

fn to_css<W>(&self, dest: &mut CssWriter<'_, W>) -> Result<(), Error>where
    W: Write,

Serialize self in CSS syntax, writing to dest.

fn to_css_string(&self) -> String

Serialize self in CSS syntax and return a string.

impl ToResolvedValue for RGBA

type ResolvedValue = RGBA

The resolved value type we’re going to be converted to.

fn to_resolved_value(self, _: &Context<'_>) -> Self

Convert a resolved value to a resolved value.

fn from_resolved_value(resolved: Self::ResolvedValue) -> Self

Convert a resolved value to resolved value form.

impl ToShmem for RGBA

fn to_shmem(
    &self,
    _builder: &mut SharedMemoryBuilder
) -> Result<ManuallyDrop<RGBA>, String>

Clones this value into a form suitable for writing into a SharedMemoryBuilder.

impl Copy for RGBA

impl StructuralPartialEq for RGBA
