Struct style::values::specified::Opacity

pub struct Opacity(Number);

The value of Opacity is , which is “ | ”. However, we serialize the specified value as number, so it’s ok to store the Opacity as Number.

Tuple Fields

0: Number

Trait Implementations

impl Clone for Opacity

fn clone(&self) -> Opacity

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Opacity

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

Formats the value using the given formatter.

impl MallocSizeOf for Opacity

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

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

impl Parse for Opacity

fn parse<'i, 't>( context: &ParserContext<'_>, input: &mut Parser<'i, 't>, ) -> Result<Self, ParseError<'i>>

Opacity accepts | , so we parse it as NumberOrPercentage, and then convert into an Number if it’s a Percentage. https://drafts.csswg.org/cssom/#serializing-css-values

impl PartialEq for Opacity

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

fn partial_cmp(&self, other: &Opacity) -> 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 SpecifiedValueInfo for Opacity

const SUPPORTED_TYPES: u8 = 0u8

Supported CssTypes by the given value type.

fn collect_completion_keywords(_f: &mut dyn FnMut(&[&'static str]))

Collect value starting words for the given specified value type. This includes keyword and function names which can appear at the beginning of a value of this type.

impl ToComputedValue for Opacity

type ComputedValue = f32

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

fn to_computed_value(&self, context: &Context<'_>) -> CSSFloat

Convert a specified value to a computed value, using itself and the data inside the Context.

fn from_computed_value(computed: &CSSFloat) -> Self

Convert a computed value to specified value form.

impl ToCss for Opacity

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

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 ToShmem for Opacity

fn to_shmem(&self, builder: &mut SharedMemoryBuilder) -> Result<Self>

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

impl Copy for Opacity

impl StructuralPartialEq for Opacity
