Required Methods§

source

fn containing_shadow_root_for_layout( self ) -> Option<LayoutDom<'dom, ShadowRoot>>

source

fn is_element_for_layout(self) -> bool

source

unsafe fn get_flag(self, flag: NodeFlags) -> bool

source

unsafe fn set_flag(self, flag: NodeFlags, value: bool)

source

fn children_count(self) -> u32

source

fn style_data(self) -> Option<&'dom StyleData>

source

fn layout_data(self) -> Option<&'dom GenericLayoutData>

source

unsafe fn initialize_style_data(self)

Initialize the style data of this node.

Safety

This method is unsafe because it modifies the given node during layout. Callers should ensure that no other layout thread is attempting to read or modify the opaque layout data of this node.

source

unsafe fn initialize_layout_data(self, data: Box<GenericLayoutData>)

Initialize the opaque layout data of this node.

Safety

This method is unsafe because it modifies the given node during layout. Callers should ensure that no other layout thread is attempting to read or modify the opaque layout data of this node.

source

unsafe fn clear_style_and_layout_data(self)

Clear the style and opaque layout data of this node.

Safety

This method is unsafe because it modifies the given node during layout. Callers should ensure that no other layout thread is attempting to read or modify the opaque layout data of this node.
