Trait Interface 

pub unsafe trait Interface: Sized {
    type Impl;
    type Vtable;

    const IID: &'static str;

    // Provided methods
    unsafe fn from_raw(raw: *mut Self::Impl) -> Self { ... }
    fn into_raw(self) -> *mut Self::Impl { ... }
    fn as_raw(&self) -> *mut Self::Impl { ... }
    fn cast<I: Interface>(&self) -> Result<I> { ... }
}

Safety

All unsafe implementers of this trait should guarantee ffi::IADLXInterface is the base type.

The struct must have the same layout as *mut IADLXInterface, preferably in terms of InterfaceImpl for automatic refcount management.

Required Associated Constants

const IID: &'static str

Required Associated Types

type Impl

type Vtable

Provided Methods

unsafe fn from_raw(raw: *mut Self::Impl) -> Self

Creates an Interface by taking ownership of the raw COM/ADLX interface pointer.

Safety

The raw pointer must be owned by the caller and represent a valid ADLX interface pointer. In other words, it must point to a vtable beginning with the ffi::IADLXInterfaceVtbl function pointers and match the vtable of Self::Vtable.

fn into_raw(self) -> *mut Self::Impl

Returns the raw COM/ADLX interface pointer and abandons ownership. It is the caller’s responsibility to release the COM/ADLX interface pointer.

fn as_raw(&self) -> *mut Self::Impl

Returns the raw COM/ADLX interface pointer. The resulting pointer continues to be owned by the Interface implementation.

fn cast<I: Interface>(&self) -> Result<I>

Dyn Compatibility

This trait is not dyn compatible.

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