Expand description

A notification that can be sent through multiple channels.

Notifications encapsulate a message that should be delivered to users through one or more channels (mail, database, slack, etc.).

§Example

use ferro_notifications::{Notification, Channel, MailMessage, DatabaseMessage};

struct OrderShipped {
    order_id: i64,
    tracking_number: String,
}

impl Notification for OrderShipped {
    fn via(&self) -> Vec<Channel> {
        vec![Channel::Mail, Channel::Database]
    }

    fn to_mail(&self) -> Option<MailMessage> {
        Some(MailMessage::new()
            .subject("Your order has shipped!")
            .body(format!("Tracking: {}", self.tracking_number)))
    }

    fn to_database(&self) -> Option<DatabaseMessage> {
        Some(DatabaseMessage::new("order_shipped")
            .data("order_id", self.order_id)
            .data("tracking", &self.tracking_number))
    }
}
