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: infoflow.rs
    path of file: ./repos/flowistry/crates/flowistry/benches/tests/max
    
    the code of the file until where you have to start completion: extern crate bench_utils;
use bench_utils::generate_flow;

pub fn main() {
  // This macro generates twice as many locations as generate_unique_lifetimes
  // and generate_locations
    
pub fn main() {
  // This macro generates twice as many locations as generate_unique_lifetimes
  // and generate_locations because each iteration creates a place and then reassigns
  // the "main" variable using that place as an input (two distinct steps). To exert 
  // equivalent location stress as done in lifetimes_unique.rs and locations.rs, we 
  // divide the number of iterations by two (1000 / 2).
  generate_flow!(_x: [i32; 500] = 1);
