pub struct Descriptor {
    pub components: Vec<Component>,
    specified: Option<Box<str>>,
}

Fields

components: Vec<Component>

The parsed components, if any. TODO: Could be a Box<[]> if that supported const construction.

specified: Option<Box<str>>

The specified css syntax, if any.

Implementations

impl Descriptor

pub const fn universal() -> Self

Returns the universal descriptor.

pub fn is_universal(&self) -> bool

Returns whether this is the universal syntax descriptor.

pub fn specified_string(&self) -> Option<&str>

Returns the specified string, if any.

pub fn from_str(css: &str, save_specified: bool) -> Result<Self, ParseError>

Parse a syntax descriptor. https://drafts.css-houdini.org/css-properties-values-api-1/#consume-a-syntax-definition

pub fn dependent_types(&self) -> DependentDataTypes

Returns the dependent types this syntax might contain.

Trait Implementations

impl Clone for Descriptor

fn clone(&self) -> Descriptor

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Descriptor

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

Formats the value using the given formatter.

impl Default for Descriptor

fn default() -> Descriptor

Returns the “default value” for a type.

impl MallocSizeOf for Descriptor

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 Descriptor

fn parse<'i>( _: &ParserContext<'_>, parser: &mut CSSParser<'i, '_>, ) -> Result<Self, StyleParseError<'i>>

Parse a syntax descriptor.

impl PartialEq for Descriptor

fn eq(&self, other: &Descriptor) -> 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 ToCss for Descriptor

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.
