Trait cpp_utils::DynamicCast

pub trait DynamicCast<T> {
    fn dynamic_cast(&self) -> Option<&T>;
    fn dynamic_cast_mut(&mut self) -> Option<&mut T>;
}

Provides access to C++ dynamic_cast conversion.

This trait is automatically implemented by cpp_to_rust. If T1 class is derived (in C++) from T2 class, DynamicCast<T1> is implemented for T2. Use StaticCast to convert from T1 to T2.

DynamicCast allows to convert a reference to a class into a reference to a derived class with a runtime check of the type. Conversion returns None if the object is actually not an instance of the target type.

dynamic_cast and dynamic_cast_mut free functions can be used to convert pointer types.

Required Methods

fn dynamic_cast(&self) -> Option<&T>

Convert type of a const reference. Returns None if self is not an instance of T.

fn dynamic_cast_mut(&mut self) -> Option<&mut T>

Convert type of a mutable reference. Returns None if self is not an instance of T.
