Enum style::properties::PropertyDeclarationId

pub enum PropertyDeclarationId<'a> {
    Longhand(LonghandId),
    Custom(&'a Name),
}

An identifier for a given property declaration, which can be either a longhand or a custom property.

Variants

Longhand(LonghandId)

A longhand.

Custom(&'a Name)

A custom property declaration.

Implementations

impl<'a> PropertyDeclarationId<'a>

pub fn flags(&self) -> PropertyFlags

Returns PropertyFlags for given property.

pub fn to_owned(&self) -> OwnedPropertyDeclarationId

Convert to an OwnedPropertyDeclarationId.

pub fn is_or_is_longhand_of(&self, other: &PropertyId) -> bool

Whether a given declaration id is either the same as other, or a longhand of it.

pub fn is_longhand_of(&self, shorthand: ShorthandId) -> bool

Whether a given declaration id is a longhand belonging to this shorthand.

pub fn name(&self) -> Cow<'static, str>

Returns the name of the property without CSS escaping.

pub fn as_longhand(&self) -> Option<LonghandId>

Returns longhand id if it is, None otherwise.

pub fn is_logical(&self) -> bool

Return whether this property is logical.

pub fn to_physical(&self, wm: WritingMode) -> Self

If this is a logical property, return the corresponding physical one in the given writing mode.

Otherwise, return unchanged.

pub fn is_animatable(&self) -> bool

Returns whether this property is animatable.

pub fn is_discrete_animatable(&self) -> bool

Returns whether this property is animatable in a discrete way.

Trait Implementations

impl<'a> Clone for PropertyDeclarationId<'a>

fn clone(&self) -> PropertyDeclarationId<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for PropertyDeclarationId<'a>

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

Formats the value using the given formatter.

impl<'a> MallocSizeOf for PropertyDeclarationId<'a>

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<'a> PartialEq for PropertyDeclarationId<'a>

fn eq(&self, other: &PropertyDeclarationId<'a>) -> 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<'a> ToCss for PropertyDeclarationId<'a>

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.
