use std::thread;
use snowflake_rs::{SnowFlakeId, STANDARD_EPOCH};

fn main() {
	let mut id_gen = SnowFlakeId::new(1, STANDARD_EPOCH);
	println!("{:?}",&id_gen);
	for _ in 1..1000 {
		let id = id_gen.generate_id();
		assert!(id.is_ok());
		println!("{:?}",id.unwrap());
	}
}

```

multi thread example
```rust
extern crate snowflake_rs;

use std::thread;
use snowflake_rs::{SnowFlakeId, STANDARD_EPOCH};

fn main() {
  let id_gen = SnowFlakeId::new_multi_thread(2, STANDARD_EPOCH);
  let mut ths = Vec::new();
  for _i in 1 .. 10{
    let t = id_gen.clone();
      ths.push(thread::spawn(move || {
      for _ in 1..1000 {
        let mut gen = t.lock().unwrap();
        let id = gen.generate_id();
        assert!(id.is_ok());
        println!("{:?}",id.unwrap());
      }
    }));
  }

  for t in ths {
    t.join();
