RUST Connect And Run Query against MySQL

Before we create the codes to connect to MySQL and retrieve it, we need to reference the MySQL crate.

extern crate mysql;

Then, we need to create a struct that resembles and represents the persons table.

#[derive(Debug, PartialEq, Eq)]
struct Person {
    person_id: i32,
    person_name: String
}

In the main function, we first get a connection:

let pool = mysql::Pool::new("mysql://root:a1128f69-e6f7-4e93-a2df-3d4db6030abc@localhost:3306/turretadb").unwrap();


Note that we are passing both the database user name and password. With a database connection, we can now retrieve records from the persons table.

let all_persons: Vec<Person> =
        pool.prep_exec("SELECT person_id, person_name from person", ())
 
            .map(|result| {
                result.map(|x| x.unwrap()).map(|row| {
                    let (person_id, person_name) = mysql::from_row(row);
 
                    Person {
                        person_id,
                        person_name
                    }
                }).collect()
            }).unwrap(); 
 
    for person in all_persons.iter() {
        println!("{}: {}", person.person_id, person.person_name);
    }


Finally, we test the application. When we run our application, we get the following output.

C:/Users/user/.cargo/bin/cargo.exe run --color=always --package rust-project1 --bin rust-project1
   Compiling rust-project1 v0.1.0 (C:\Users\user\Desktop\dev\rust-MYSQL-Example)
