You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: mod.rs
    path of file: ./repos/windows-rs/crates/libs/windows/src/Windows/Devices/Sensors/Custom
    
    the code of the file until where you have to start completion: windows_core::imp::define_interface!(ICustomSensor, ICustomSensor_Vtbl, 0xa136f9ad_4034_4b4d_99dd_531
    
    pub fn DeviceId(&self) -> windows_core::Result<windows_core::HSTRING> {
        let this = self;
        unsafe {
            let mut result__ = std::mem::zeroed();
            (windows_core::Interface::vtable(this).DeviceId)(windows_core::Interface::as_raw(this), &mut result__).and_then(|| windows_core::Type::from_abi(result__))
        }
    }
