Trait DynTrait 

pub trait DynTrait {
    type Vtable: 'static;

    // Required methods
    fn drop_in_place_fn(vtable: &Self::Vtable) -> Option<unsafe fn(NonNull<()>)>;
    fn layout(vtable: &Self::Vtable) -> Layout;
}

A trait object with its associated vtable.

Required Associated Types

type Vtable: 'static

The trait object vtable.

Required Methods

fn drop_in_place_fn(vtable: &Self::Vtable) -> Option<unsafe fn(NonNull<()>)>

Returns the drop function of the trait object as stored in vtable.

fn layout(vtable: &Self::Vtable) -> Layout

Returns the layout of the trait object as stored in vtable.

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.
