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: properties.rs
    path of file: ./repos/vulkano/vulkano/autogen
    
    the code of the file until where you have to start completion: use super::{write_file, IndexMap, VkRegistryData};
use ahash::HashMap;
use heck::ToSnakeCase;
use nom::{
    bytes::complete::{tag, take_until, take_while1},
    character::complete::{self, digit1},
    combinator::{all_consuming, eof},
    sequence::{delimited, tuple},
    IResult,
};
use proc_macro2::{Ide
    
pub fn write(vk_data: &VkRegistryData) {
    let properties_output = properties_output(&properties_members(&vk_data.types));
    let properties_ffi_output =
        properties_ffi_output(&properties_ffi_members(&vk_data.types, &vk_data.extensions));
    write_file(
        "properties.rs",
        format!(
            "vk.xml header version {}.{}.{}",
            vk_data.header_version.0, vk_data.header_version.1, vk_data.header_version.2
        ),
        quote! {
            #properties_output
            #properties_ffi_output
        },
    );
}
