Trait dyn_dyn::GetDynDynTable

pub unsafe trait GetDynDynTable<B: ?Sized + DynDynBase> {
    type DynTarget: ?Sized + Unsize<B>;

    fn get_dyn_dyn_table(&self) -> DynDynTable;
}

A pointer to an object which has a DynDynTable associated with it.

Safety

• If this type implements Deref, then the reference returned by calling Deref::deref must not change for the lifetime of this pointer unless the pointer itself is mutated.
• If this type implements DerefMut, then the reference returned by calling DerefMut::deref_mut must not change for the lifetime of this pointer unless the pointer itself is mutated and must point to the same object as a reference returned by calling Deref::deref, including having identical metadata. Additionally, calling DerefMut::deref_mut must not mutate the pointer.
• If this type implements Deref, then the reference returned by calling Deref::deref must be unsize-coercible to a reference to GetDynDynTable::get_dyn_dyn_table.
• If this type implements Deref, then the returned table must be equivalent to calling GetDynDynTable::get_dyn_dyn_table on a reference returned by calling Deref::deref.
• If this type implements DowncastUnchecked<B>, then the result of calling DowncastUnchecked::downcast_unchecked with metadata retrieved from the table returned by calling GetDynDynTable::get_dyn_dyn_table on this pointer shall be valid and safe to use.

Required Associated Types

type DynTarget: ?Sized + Unsize<B>

The actual type that this pointer currently points to. This type is used to allow propagation of auto trait bounds such as Send and Sync in the dyn_dyn_cast! macro.

Required Methods

fn get_dyn_dyn_table(&self) -> DynDynTable

Gets the DynDynTable for the object that this pointer points to.
