Methods on mutable raw pointers

Required Methods

type Target

unsafe fn as_mut(&self) -> Option<&'a mut <Self as MutPtrExt>::Target>

Returns None if the pointer is null, or else returns a mutable reference to the value wrapped in Some.

Safety

As with as_ref, this is unsafe because it cannot verify the validity of the returned pointer.
