Struct script::dom::bindings::root::LayoutDom

pub struct LayoutDom<'dom, T> {
    value: &'dom T,
}

An unrooted reference to a DOM object for use in layout. Layout*Helpers traits must be implemented on this.

Fields

value: &'dom T

Implementations

impl<'dom, T> LayoutDom<'dom, T>where
    T: Castable,

pub fn upcast<U>(&self) -> LayoutDom<'dom, U>where
    U: Castable,
    T: DerivedFrom<U>,

Cast a DOM object root upwards to one of the interfaces it derives from.

pub fn downcast<U>(&self) -> Option<LayoutDom<'dom, U>>where
    U: DerivedFrom<T>,

Cast a DOM object downwards to one of the interfaces it might implement.

pub fn is<U>(&self) -> boolwhere
    U: DerivedFrom<T>,

Returns whether this inner object is a U.

impl<T> LayoutDom<'_, T>where
    T: DomObject,

pub unsafe fn get_jsobject(&self) -> *mut JSObject

Get the reflector.

impl LayoutDom<'_, Node>

pub unsafe fn from_trusted_node_address(inner: TrustedNodeAddress) -> Self

Create a new JS-owned value wrapped from an address known to be a Node pointer.

impl<'dom, T> LayoutDom<'dom, T>where
    T: 'dom + DomObject,

pub unsafe fn unsafe_get(self) -> &'dom T

Returns a reference to the interior of this JS object. The fact that this is unsafe is what necessitates the layout wrappers.

pub unsafe fn to_layout_slice(
    slice: &'dom [Dom<T>]
) -> &'dom [LayoutDom<'dom, T>]

Transforms a slice of Dom into a slice of LayoutDom.
