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: simple.rs
    path of file: ./repos/oxc/crates/oxc_semantic/examples
    
    the code of the file until where you have to start completion: use std::{env, path::Path, sync::Arc};

use itertools::Itertools;
use oxc_allocator::Allocator;
use oxc_parser::Parser;
use oxc_semantic::SemanticBuilder;
use oxc_span::SourceType;

// Instruction:
// create a `test.js`,
// run `cargo run -p oxc_semantic --example simple`
// or `just watch "run -p oxc_semantic --example simple"`

fn main() -> std::io::Result<()> {
    let name = env::args().nth(1).unwrap_or_else(|| "test.js".to_string());
    let path = Path::new(&name);
    let source_text = Arc::new(std::fs::read_to_string(path)?);
    let allocator = Allocator::default();
    let source_type = SourceType::from_path(path).unwrap();
    let ret = Parser::new(&allocator, &source_text, source_type).parse();

    let program = allocator.alloc(ret.program);

    let semantic = SemanticBuilder::new(&source_text, source_type)
        .
    
fn main() -> std::io::Result<()> {
    let name = env::args().nth(1).unwrap_or_else(|| "test.js".to_string());
    let path = Path::new(&name);
    let source_text = Arc::new(std::fs::read_to_string(path)?);
    let allocator = Allocator::default();
    let source_type = SourceType::from_path(path).unwrap();
    let ret = Parser::new(&allocator, &source_text, source_type).parse();

    let program = allocator.alloc(ret.program);

    let semantic = SemanticBuilder::new(&source_text, source_type)
        .with_check_syntax_error(true)
        .with_trivias(ret.trivias)
        .build(program);

    if !semantic.errors.is_empty() {
        let error_message: String = semantic
            .errors
            .into_iter()
            .map(|error| error.with_source_code(Arc::clone(&source_text)).to_string())
            .join("\n\n");

        println!("Semantic analysis failed:\n\n{error_message}",);
    }

    Ok(())
