Trait Pointer 

pub trait Pointer: Sized {
    type Target;

    // Required methods
    fn as_ref(&self) -> &Self::Target;
    unsafe fn from_raw(p: *const Self::Target) -> Self;
    fn into_raw(self) -> *const Self::Target;

    // Provided method
    fn as_ptr(&self) -> *const Self::Target { ... }
}

Abstract pointer trait to support various pointer types in collections.

This trait allows the collections to work with:

• Box<T>: Owned, automatically dropped.
• Arc<T>: Shared ownership.
• Rc<T>: Single thread ownership.
• NonNull<T>: Raw non-null pointers (manual memory management).
• *const T: Raw pointers (recommend to use NonNull<T> instead)

Required Associated Types

type Target

Required Methods

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

unsafe fn from_raw(p: *const Self::Target) -> Self

Safety

must be pointer acquire from Self::into_raw()

fn into_raw(self) -> *const Self::Target

Provided Methods

fn as_ptr(&self) -> *const Self::Target

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
