Trait owned_pin::RawConvertable

pub unsafe trait RawConvertable: Deref {
    type Metadata: Sized;

    // Required methods
    fn into_raw(this: Self) -> (NonNull<Self::Target>, Self::Metadata);
    unsafe fn from_raw(
        pointer: NonNull<Self::Target>,
        metadata: Self::Metadata
    ) -> Self;
}

Smart pointers that can convert themselves into raw forms, and is able to convert raw forms back to themselves.

Safety

The implementor of this trait must enable any valid raw form to be converted back to its corresponding valid smart pointer.

Required Associated Types

type Metadata: Sized

The additional metadata needed to be converted back.

Required Methods

fn into_raw(this: Self) -> (NonNull<Self::Target>, Self::Metadata)

Converts a smart pointer into its raw form.

unsafe fn from_raw( pointer: NonNull<Self::Target>, metadata: Self::Metadata ) -> Self

Converts the raw form of a smart pointer back.

Safety

pointer and metadata must be the ones that is previously returned from the same call of into_raw.

Object Safety

This trait is not object safe.
