}

https://drafts.csswg.org/css-contain-2/#content-visibility

Variants

Auto

auto variant, the element turns on layout containment, style containment, and paint containment. In addition, if the element is not relevant to the user (such as by being offscreen) it also skips its content

Hidden

hidden variant, the element skips its content

Visible

‘visible’ variant, no effect

Implementations

impl ContentVisibility

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

Parse this keyword.

pub fn from_ident(ident: &str) -> Result<Self, ()>

Parse this keyword from a string slice.

Trait Implementations

impl Clone for ContentVisibility

fn clone(&self) -> ContentVisibility

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ContentVisibility

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ContentVisibility

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl MallocSizeOf for ContentVisibility

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 ContentVisibility

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

Parse a value of this type.

impl PartialEq<ContentVisibility> for ContentVisibility

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

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.

impl SpecifiedValueInfo for ContentVisibility

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 ContentVisibility

type ComputedValue = ContentVisibility

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

fn from_computed_value(from: &Self::ComputedValue) -> Self

Convert a computed value to specified value form.

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

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

impl ToCss for ContentVisibility

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

type ResolvedValue = ContentVisibility

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

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

Convert a resolved value to resolved value form.

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

Convert a resolved value to a resolved value.

impl ToShmem for ContentVisibility

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

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

impl Copy for ContentVisibility

impl Eq for ContentVisibility

impl StructuralEq for ContentVisibility
