Dynamic-rs

Inheritance in rust

This library provides runtime type information for dynamic casting(upcast/downcast) using LLVM-style RTTI

Usages

```rust

[subclass(DynamicObjectBase)]

struct Class { value: u32, foo: u32 }

[subclass(Class, parent)]

struct Derived { field: u32, parent: Class, }

let object = Derived { parent: Class { value: 548389, foo: 72840548 }, field: 2153746, };

let object = Object::::new(Box::new(object));

assert!(object.field == 2153746); assert!(object.parent.value == 548389); assert!(object.parent.foo == 72840548);

// Downcast let object = object.cast::(); assert!(object.value == 548389); assert!(object.foo == 72840548);

// Upcast let object = object.cast::(); assert!(object.field == 2153746); assert!(object.parent.value == 548389); assert!(object.parent.foo == 72840548); ```

To use virtual methods rust // Set second generic argument to your trait type MyObject = Object<MyClass, Box<dyn MyTrait>> // And access the vtable by object.vtable().method(); // Or object.vtable_mut().methid();
