Struct script::dom::bindings::import::module::jsapi::MutableHandle

#[repr(C)]
pub struct MutableHandle<T> {
    pub _phantom_0: PhantomData<UnsafeCell<T>>,
    pub ptr: *mut T,
}

Similar to a handle, but the underlying storage can be changed. This is useful for outparams.

If you want to add additional methods to MutableHandle for a specific specialization, define a MutableHandleOperations specialization containing them.

Fields

_phantom_0: PhantomData<UnsafeCell<T>>

ptr: *mut T

Trait Implementations

impl<T> Clone for MutableHandle<T>

where T: Clone,

fn clone(&self) -> MutableHandle<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for MutableHandle<T>

where T: Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<T> Deref for MutableHandle<T>

type Target = T

The resulting type after dereferencing.

fn deref<'a>(&'a self) -> &'a T

Dereferences the value.

impl<T> DerefMut for MutableHandle<T>

fn deref_mut<'a>(&'a mut self) -> &'a mut T

Mutably dereferences the value.

impl<T> From<T> for MutableHandle<<T as IntoHandle>::Target>

where T: IntoMutableHandle,

fn from(value: T) -> MutableHandle<<T as IntoHandle>::Target>

Converts to this type from the input type.

impl<T> PartialEq for MutableHandle<T>

where T: PartialEq,

fn eq(&self, other: &MutableHandle<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T> Copy for MutableHandle<T>

where T: Copy,
