Struct script::dom::bindings::principals::ServoJSPrincipalsRef

pub struct ServoJSPrincipalsRef<'a>(ManuallyDrop<ServoJSPrincipals>, PhantomData<&'a ()>);

A borrowed reference to Servo’s JSPrincipals instance. Does not update the reference count on creation and deletion.

Tuple Fields

0: ManuallyDrop<ServoJSPrincipals>

1: PhantomData<&'a ()>

Implementations

impl ServoJSPrincipalsRef<'_>

pub unsafe fn from_raw_nonnull(raw: NonNull<JSPrincipals>) -> Self

Construct Self from a raw NonNull<JSPrincipals>.

Safety

ServoJSPrincipalsRef does not update the reference count of the wrapped JSPrincipals object. It’s up to the caller to ensure the returned ServoJSPrincipalsRef object or any clones are not used past the lifetime of the wrapped object.

pub unsafe fn from_raw_unchecked(raw: *mut JSPrincipals) -> Self

Construct Self from a raw *mut JSPrincipals.

Safety

The behavior is undefined if raw is null. See also Self::from_raw_nonnull.

Trait Implementations

impl Clone for ServoJSPrincipalsRef<'_>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Deref for ServoJSPrincipalsRef<'_>

type Target = ServoJSPrincipals

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
