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: compile_many.rs
    path of file: ./repos/ethers-rs/ethers-solc/benches
    
    the code of the file until where you have to start completion: //! compile many benches
#[macro_use]
extern crate criterion;

use criterion::Criterion;
use ethers_solc::{CompilerInput, Solc};
use std::path::Path;

fn compile_many_benchmark(c: &mut Criterion) {
    let inputs = load_compiler_inputs();
    let solc = Solc::default();

    let mut group = c.benchmark_group("compile many");
    group.sample_size(10);
    group.bench_function("sequential", |
    
fn load_compiler_inputs() -> Vec<CompilerInput> {
    let mut inputs = Vec::new();
    for file in std::fs::read_dir(Path::new(&env!("CARGO_MANIFEST_DIR")).join("test-data/in"))
        .unwrap()
        .take(5)
    {
        let file = file.unwrap();
        let input = std::fs::read_to_string(file.path()).unwrap();
        let input: CompilerInput = serde_json::from_str(&input).unwrap();
        inputs.push(input);
    }
    inputs
}
