A trait to represent a given stylesheet in a document.

Required Methods

fn enabled(&self) -> bool

Get whether this stylesheet is enabled.

fn media<'a>( &'a self, guard: &'a SharedRwLockReadGuard<'_>, ) -> Option<&'a MediaList>

Get the media associated with this stylesheet.

fn contents(&self) -> &StylesheetContents

Returns a reference to the contents of the stylesheet.

fn implicit_scope_root(&self) -> Option<ImplicitScopeRoot>

Return the implicit scope root for this stylesheet, if one exists.

Provided Methods

fn rules<'a, 'b: 'a>( &'a self, guard: &'b SharedRwLockReadGuard<'_>, ) -> &'a [CssRule]

Returns a reference to the list of rules in this stylesheet.

fn iter_rules<'a, 'b, C>( &'a self, device: &'a Device, guard: &'a SharedRwLockReadGuard<'b>, ) -> RulesIterator<'a, 'b, C>

where C: NestedRuleIterationCondition,

Return an iterator using the condition C.

fn is_effective_for_device( &self, device: &Device, guard: &SharedRwLockReadGuard<'_>, ) -> bool

Returns whether the style-sheet applies for the current device.

fn effective_rules<'a, 'b>( &'a self, device: &'a Device, guard: &'a SharedRwLockReadGuard<'b>, ) -> EffectiveRulesIterator<'a, 'b>

Return an iterator over the effective rules within the style-sheet, as according to the supplied Device.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
