Attribute Macro pipewire_wrapper_proc_macro::object_type_impl

#[object_type_impl]

Add an *Info and *Builder structures after the enum definition. For each enum variant will be added optional struct fields with value and flags.

Examples

Derive:

#[allow(non_camel_case_types)]
#[derive(Debug)]
#[repr(u32)]
#[object_info(OBJECT_PROPS)]
pub enum ObjectPropType<'a> {
    // Device
    DEVICE(&'a PodStringRef) = Prop::DEVICE.raw,
    DEVICE_NAME(&'a PodStringRef) = Prop::DEVICE_NAME.raw,

}

Usage:

if let Ok(BasicType::OBJECT(object)) = param.downcast() {
    match object.body_type() {
        Type::OBJECT_PROP_INFO => {
            let info = ObjectPropInfoInfo::try_from(object).unwrap();
            println!("Prop info: {:?}", info);
        }
        _ => todo!(),
    }
}
