Type Alias MysqlConnection 

pub type MysqlConnection = MysqlLikeConnection<Mysql>;

Available on crate features mysql_backend and mysql only.

A connection to a MySQL database. Connection URLs should be in the form mysql://[user[:password]@]host/database_name[?unix_socket=socket-path&ssl_mode=SSL_MODE*&ssl_ca=/etc/ssl/certs/ca-certificates.crt&ssl_cert=/etc/ssl/certs/client-cert.crt&ssl_key=/etc/ssl/certs/client-key.crt]

• host can be an IP address or a hostname. If it is set to localhost, a connection will be attempted through the socket at /tmp/mysql.sock. If you want to connect to a local server via TCP (e.g. docker containers), use 0.0.0.0 or 127.0.0.1 instead.
• unix_socket expects the path to the unix socket
• ssl_ca accepts a path to the system’s certificate roots
• ssl_cert accepts a path to the client’s certificate file
• ssl_key accepts a path to the client’s private key file
• ssl_mode expects a value defined for MySQL client command option --ssl-mode See https://dev.mysql.com/doc/refman/5.7/en/connection-options.html#option_general_ssl-mode

Errors carry the SQLSTATE the server or client library reports in DatabaseErrorInformation::sqlstate, including custom codes raised with SIGNAL. The server reports HY000 for errors without a specific SQLSTATE, as described at https://dev.mysql.com/doc/refman/8.4/en/error-message-elements.html.

Supported loading model implementations

• DefaultLoadingMode

As MysqlConnection only supports a single loading mode implementation it is not required to explicitly specify a loading mode when calling RunQueryDsl::load_iter() or LoadConnection::load

DefaultLoadingMode

MysqlConnection only supports a single loading mode, which loads values row by row from the result set.

use diesel::connection::DefaultLoadingMode;
{
    // scope to restrict the lifetime of the iterator
    let iter1 = users::table.load_iter::<(i32, String), DefaultLoadingMode>(connection)?;

    for r in iter1 {
        let (id, name) = r?;
        println!("Id: {} Name: {}", id, name);
    }
}

// works without specifying the loading mode
let iter2 = users::table.load_iter::<(i32, String), _>(connection)?;

for r in iter2 {
    let (id, name) = r?;
    println!("Id: {} Name: {}", id, name);
}

This mode does not support creating multiple iterators using the same connection.

use diesel::connection::DefaultLoadingMode;

let iter1 = users::table.load_iter::<(i32, String), DefaultLoadingMode>(connection)?;
let iter2 = users::table.load_iter::<(i32, String), DefaultLoadingMode>(connection)?;

for r in iter1 {
    let (id, name) = r?;
    println!("Id: {} Name: {}", id, name);
}

for r in iter2 {
    let (id, name) = r?;
    println!("Id: {} Name: {}", id, name);
}
