Enum style::values::specified::text::TextAlign

pub enum TextAlign {
    Keyword(TextAlignKeyword),
    MozCenterOrInherit,
}

Specified value of text-align property.

Variants

Keyword(TextAlignKeyword)

Keyword value of text-align property.

MozCenterOrInherit

This is how we implement the following HTML behavior from https://html.spec.whatwg.org/#tables-2:

User agents are expected to have a rule in their user agent style sheet
that matches th elements that have a parent node whose computed value
for the 'text-align' property is its initial value, whose declaration
block consists of just a single declaration that sets the 'text-align'
property to the value 'center'.

Since selectors can’t depend on the ancestor styles, we implement it with a magic value that computes to the right thing. Since this is an implementation detail, it shouldn’t be exposed to web content.

Trait Implementations

impl Clone for TextAlign

fn clone(&self) -> TextAlign

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TextAlign

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

Formats the value using the given formatter.

impl Hash for TextAlign

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl MallocSizeOf for TextAlign

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 TextAlign

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

Parse a value of this type.

impl PartialEq for TextAlign

fn eq(&self, other: &TextAlign) -> 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 SpecifiedValueInfo for TextAlign

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 TextAlign

type ComputedValue = TextAlignKeyword

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

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.

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

Convert a computed value to specified value form.

impl ToCss for TextAlign

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 TextAlign

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

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

impl Copy for TextAlign

impl Eq for TextAlign

impl StructuralPartialEq for TextAlign
