Implementations

impl Attr

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

Parse contents of attr() assuming we have already parsed attr and are within a parse_nested_block()

Trait Implementations

impl Clone for Attr

fn clone(&self) -> Attr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Attr

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

Formats the value using the given formatter.

impl MallocSizeOf for Attr

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 Attr

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

Parse a value of this type.

impl PartialEq for Attr

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

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 Attr

where Prefix: ToComputedValue<ComputedValue = Prefix>, Namespace: ToComputedValue<ComputedValue = Namespace>, Atom: ToComputedValue<ComputedValue = Atom>, AtomString: ToComputedValue<ComputedValue = AtomString>,

type ComputedValue = Attr

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 Attr

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 ToResolvedValue for Attr

where Prefix: ToResolvedValue<ResolvedValue = Prefix>, Namespace: ToResolvedValue<ResolvedValue = Namespace>, Atom: ToResolvedValue<ResolvedValue = Atom>, AtomString: ToResolvedValue<ResolvedValue = AtomString>,

type ResolvedValue = Attr

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 Attr

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

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

impl Eq for Attr

impl StructuralPartialEq for Attr
