Trait SmartPtr 

pub trait SmartPtr: Sized {
    type Content: ?Sized;
    type Rebind<U: ?Sized>: SmartPtr<Content = U>;

    // Required methods
    unsafe fn from_alloc(p: *mut Self::Content) -> Self;
    unsafe fn rebind<U>(self) -> Self::Rebind<U>
       where U: Pointee<Metadata = <Self::Content as Pointee>::Metadata> + ?Sized;
}

An abstract of smart pointers.

Required Associated Types

type Content: ?Sized

The inner type of the pointer.

type Rebind<U: ?Sized>: SmartPtr<Content = U>

Rebind the smart pointer to another content type.

Required Methods

unsafe fn from_alloc(p: *mut Self::Content) -> Self

Create the smart pointer from pointer allocated from Global.

Safety

See Box::from_raw.

unsafe fn rebind<U>(self) -> Self::Rebind<U>

where U: Pointee<Metadata = <Self::Content as Pointee>::Metadata> + ?Sized,

Convert the smart pointer to another content type one.

Safety

See std::mem::transmute.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
