Trait PtrInit 

pub trait PtrInit<T>: Deref<Target = T> + Sized {
    type Uninit: Deref<Target = MaybeUninit<T>>;

    // Required method
    fn init<E, I>(uninit: Pin<Self::Uninit>, init: I) -> Result<Pin<Self>, E>
       where I: Init<T, E>;
}

Pointer types that can be pin-initialized.

Required Associated Types

type Uninit: Deref<Target = MaybeUninit<T>>

Required Methods

fn init<E, I>(uninit: Pin<Self::Uninit>, init: I) -> Result<Pin<Self>, E>

where I: Init<T, E>,

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.
