Struct Preview 

pub struct Preview {
    pub name: &'static str,
    pub build: fn() -> Result<Email>,
}

A mailer action shown at /ocre/dev/mailers in ocre dev, rendered with sample data, like Rails’ mailer previews.

name reads mailer/action; build returns the email, usually by calling the action with sample arguments. ocre g mailer adds one per action to PREVIEWS in src/mailers/mod.rs. Nothing is sent: the page shows the headers, the HTML (inline images included) and the text.

Examples

use ocre::mail::{Email, Preview};

fn welcome(to: &str) -> ocre::Result<Email> {
    Ok(Email::new(to, "Welcome", "Hello"))
}

static PREVIEWS: &[Preview] = &[Preview::new("user/welcome", || welcome("ada@example.com"))];
assert_eq!(PREVIEWS[0].name, "user/welcome");

Fields

name: &'static str

mailer/action, e.g. user/welcome; the page’s URL is /ocre/dev/mailers/preview/<name>.

build: fn() -> Result<Email>

Builds the email with sample data.

Implementations

impl Preview

pub const fn new(name: &'static str, build: fn() -> Result<Email>) -> Self

Examples

let preview = ocre::mail::Preview::new("user/welcome", || Ok(ocre::mail::Email::new("ada@example.com", "Hi", "Hello")));
assert_eq!((preview.build)().unwrap().subject, "Hi");
