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: stand.rs
    path of file: ./repos/uiua/src
    
    the code of the file until where you have to start completion: use std::{env, fs, io, path::Path};

use once_cell::sync::Lazy;

use crate::{Assembly, Compiler, NativeSys, UiuaResult};

co
    
fn load_asm() -> io::Result<Option<Assembly>> {
    // Read the current exe
    let bytes = fs::read(env::current_exe()?)?;
    // Check if it is a standalone exe
    let Some(bytes) = bytes.strip_suffix(STAND_DATA_SIGNATURE) else {
        return Ok(None);
    };
    // Get the length of the serialized files
    let (bytes, len_bytes) = bytes.split_at(bytes.len() - 8);
    let asm_len = u64::from_le_bytes(len_bytes.try_into().unwrap());
    let start = bytes.len() - asm_len as usize;
    // Deserialize the files
    let asm: Assembly = serde_json::from_slice(&bytes[start..])?;
    Ok(Some(asm))
}
