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/Graphics/Printing/PrintTicket
    
    the code of the file until where you have to start completion: windows_core::imp::define_interface!(IPrintTicketCapabilities, IPrintTicketCapabilities_Vtbl, 0x8c45508b_bbdc_4256_a142_2
    
    pub fn DisplayName(&self) -> windows_core::Result<windows_core::HSTRING> {
        let this = self;
        unsafe {
            let mut result__ = std::mem::zeroed();
            (windows_core::Interface::vtable(this).DisplayName)(windows_core::Interface::as_raw(this), &mut result__).and_then(|| windows_core::Type::from_abi(result__))
        }
    }
