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: windows.rs
    path of file: ./repos/MirrorX/mirrorx_core/src/component/fs
    
    the code of the file until where you have to start completion: use super::{Directory, Entry, IconType};
use crate::{core_error, error::CoreResult, HRESULT
    
pub fn read_root_directory() -> CoreResult<Directory> {
    let mut entries = Vec::new();

    unsafe {
        let mask = GetLogicalDrives();
        for i in 0..u32::BITS {
            if (mask >> i) & 1 == 0 {
                continue;
            }

            let disk = [b'A' + i as u8, b':', b'\\'];
            let disk_str = std::str::from_utf8_unchecked(&disk);
            let path = PathBuf::from_str(disk_str)?;

            let icon = read_icon(&path).ok();

            entries.push(Entry {
                is_dir: true,
                path,
                modified_time: 0,
                size: 0,
                icon: IconType::Bytes(icon),
            });
        }
    }

    Ok(Directory {
        path: PathBuf::from(r"\"),
        entries,
        hashed_icons: HashMap::new(),
    })
}
