Struct MysqlConnection 

pub struct MysqlConnection {
    pub host: String,
    pub port: u16,
    pub user: String,
    pub password: String,
    pub database: String,
    pub connect_timeout_secs: u32,
}

A resolved MySQL connection target for the client. The password goes in MYSQL_PWD (the env the mysql/mysqldump clients read), never argv.

Fields

host: String

The reachable host.

port: u16

The server port.

user: String

The role to connect as.

password: String

The password — the ONLY secret; it goes in MYSQL_PWD, never argv.

database: String

The physical database to dump/restore.

connect_timeout_secs: u32

A bounded connect timeout (seconds).

Implementations

impl MysqlConnection

pub fn env(&self) -> Vec<(String, String)>

The connection ENVIRONMENT: MYSQL_PWD (the password) ONLY. The password is the sole secret and goes in the env every MySQL client reads, never argv. Host/port/ user are NOT placed here — unlike libpq’s PGHOST (honored by all libpq tools), MYSQL_HOST is read by the mysql CLI ALONE; mysqldump ignores it and defaults to the local unix socket (“Can’t connect to local MySQL server through socket”), so the host/port/user travel in argv via conn_args.

pub fn conn_args(&self) -> Vec<String>

The non-secret connection args every MySQL client (both mysql and mysqldump) honors: --host, --port, --user. A real host IP (not “localhost”) forces TCP rather than the local socket. None of these is a credential, so argv is correct; no DSN string is assembled.
