Example code is provided at the Rust Playground for you to try out:

use std::collections::HashMap;
fn main() {
let mut myhm:HashMap<String, String> = HashMap::new();
myhm.insert("Bob".to_string(),"32".to_string());
myhm.insert("Rob".to_string(),"38".to_string());
myhm.insert("Zob".to_string(),"46".to_string());
if myhm.contains_key("Bob"){
println!("{}","Bob IS in the HashMap")
}
//println!("{:?}",myhm.get("Bkob"));
match myhm.get("Bob"){
Some(abc)=>println!("Age: {}", abc),
None => println!("Bob is NOT found")
};
for (k,v) in myhm{
if k =="Bob"{
println!("Found Bob his age is {:?}\n",v)
}
};
}
