Installation

You can add this library to your project using

Usage

For quick start, you can do the following: Based on the email client you want to support, you need to initialize email configuration as below:

async fn send_email() {
    let email = EmailObject {
        sender: "test@example.com",
        to: vec![EmailAddress { name: "Mail".to_string(), email: "to@example.com".to_string() }],
        subject: "subject".to_string(),
        plain: "plain body".to_string(),
        html: "<a>html body</a>".to_string(),
    };
    
    // Choose any of the config as below:
    // 1. Terminal client (needs terminal feature, enabled by default)
    let terminal_config: TerminalConfig = String::from("me@domain.com").into(); // Terminal config
    // 2. Smtp config (needs smtp feature)
    let smtp_config = SmtpConfig::default().sender("sender@example.com").relay("localhost");
    // 3. Memory config (needs memory feature)
    let (tx, rx) = mpsc::sync_channel(2);
    let memory_config = String::from("me@domain.com").into();
    
    let email_configuration: EmailConfiguration = terminal_config.into(); // OR any of the other config
    let client = get_email_client(email_configuration);
    client.send_emails(email).await;
    
    // For memory config, if you want to retain the receiver, you can do so using:
    let memory_client = EmailClient::Memory(MemoryClient::with_tx(memory_config, tx));
}

Testing

The tests here needs an open mail server listening locally on port 2525. You can do so using:

$ python -m smtpd -n -c DebuggingServer 127.0.0.1:2525
