Struct MutObjCell

#[repr(transparent)]
pub(crate) struct MutObjCell(ObjCell);

This represents a mutable view into an Object. See ObjCell for a more detailed explanation. Holding this type means that we confirmed that the data stucture is mutable, and we can use the MutObjCell::set method update this cell.

Implementations

impl MutObjCell

pub(crate) fn set(&self, value: Gc<ObjectType<'_>>)

Methods from Deref<Target = ObjCell>

pub(crate) fn get(&self) -> Gc<ObjectType<'_>>

pub(in core) unsafe fn as_mut( &self, ) -> &MutObjCell

Casts to a MutObjCell. Caller must ensure that the data structure is mutable.

Trait Implementations

impl PartialEq for MutObjCell

fn eq(&self, other: &MutObjCell) -> 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 Deref for MutObjCell

type Target = ObjCell

The resulting type after dereferencing.

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

Dereferences the value.
