Struct style::rule_tree::StyleSource

source ·
pub struct StyleSource(ArcUnion<Locked<StyleRule>, Locked<PropertyDeclarationBlock>>);
Expand description

A style source for the rule node. It can either be a CSS style rule or a declaration block.

Note that, even though the declaration block from inside the style rule could be enough to implement the rule tree, keeping the whole rule provides more debuggability, and also the ability of show those selectors to devtools.

Implementations§

source§

impl StyleSource

source

pub fn from_rule(rule: Arc<Locked<StyleRule>>) -> Self

Creates a StyleSource from a StyleRule.

source

pub(super) fn key(&self) -> NonNull<()>

source

pub fn from_declarations(decls: Arc<Locked<PropertyDeclarationBlock>>) -> Self

Creates a StyleSource from a PropertyDeclarationBlock.

source

pub(super) fn dump<W: Write>( &self, guard: &SharedRwLockReadGuard<'_>, writer: &mut W, )

source

pub fn read<'a>( &'a self, guard: &'a SharedRwLockReadGuard<'_>, ) -> &'a PropertyDeclarationBlock

Read the style source guard, and obtain thus read access to the underlying property declaration block.

source

pub fn as_rule(&self) -> Option<ArcBorrow<'_, Locked<StyleRule>>>

Returns the style rule if applicable, otherwise None.

source

pub fn as_declarations( &self, ) -> Option<ArcBorrow<'_, Locked<PropertyDeclarationBlock>>>

Returns the declaration block if applicable, otherwise None.
