Simple loop over a rust hashmap 02.09.22

for (k, v) in &h_source
  {
    println!("k: {} v: {} ", k, v);
  }

example: 
  let sql = "SELECT                                                                                                                                                                      
      id                                                                                                                                                                                 
      ,av0_code                                                                                                                                                                          
      ,CONVERT(varchar(30),CONVERT(datetime, [rv]),126) as rv                                                                                                                            
      FROM [SL_customer].[dbo].[av0_code]";
      println!("{}",sql);

let h_r = get_vec(sql).await.unwrap();

let mut h_source: HashMap<String, String> = HashMap::new();
  for i in &h_r
  {
    let h_code = i[1].to_string();
    let h_rv   = i[2].to_string();
    h_source.insert(h_code, h_rv);
  }

println!("{}", h_source.contains_key("14BCx"));

for (k, v) in &h_source
  {
    println!("k: {} v: {} ", k, v);
  }

Ok(())
