Crate async_mailer_outlook 

An Outlook mailer, usable either stand-alone or as either generic Mailer or dynamic dyn DynMailer.

Preferably, use async-mailer, which re-exports from this crate, rather than using async-mailer-outlook directly.

You can control the re-exported mailer implementations, as well as tracing support, via async-mailer feature toggles.

Examples

Using the statically typed Mailer:

// Both `async_mailer::OutlookMailer` and `async_mailer::SmtpMailer` implement `Mailer`
// and can be used with `impl Mailer` or `<M: Mailer>` bounds.

let mailer = OutlookMailer::new(
    "<Microsoft Identity service tenant>".into(),
    "<OAuth2 app GUID>".into(),
    secrecy::SecretString::from("<OAuth2 app secret>")
).await?;

// An alternative `SmtpMailer` can be found at `async-mailer-smtp`.
// Further alternative mailers can be implemented by third parties.

// Build a message using the re-exported `mail_builder::MessageBuilder'.
//
// For blazingly fast rendering of beautiful HTML mail,
// I recommend combining `askama` with `mrml`.

let message = async_mailer_core::mail_send::mail_builder::MessageBuilder::new()
    .from(("From Name", "from@example.com"))
    .to("to@example.com")
    .subject("Subject")
    .text_body("Mail body")
    .into_message()?;

// Send the message using the statically typed `Mailer`.

mailer.send_mail(message).await?;

Using the dynamically typed DynMailer:

// Both `async_mailer::OutlookMailer` and `async_mailer::SmtpMailer`
// implement `DynMailer` and can be used as trait objects.
//
// Here they are used as `BoxMailer`, which is an alias to `Box<dyn DynMailer>`.

let mailer: BoxMailer = OutlookMailer::new_box( // Or `OUtlookMailer::new_arc()`.
    "<Microsoft Identity service tenant>".into(),
    "<OAuth2 app GUID>".into(),
    secrecy::SecretString::from("<OAuth2 app secret>")
).await?;

// An alternative `SmtpMailer` can be found at `async-mailer-smtp`.
// Further alternative mailers can be implemented by third parties.

// The trait object is `Send` and `Sync` and may be stored e.g. as part of your server state.

// Build a message using the re-exported `mail_builder::MessageBuilder'.
//
// For blazingly fast rendering of beautiful HTML mail,
// I recommend combining `askama` with `mrml`.

let message = async_mailer_core::mail_send::mail_builder::MessageBuilder::new()
    .from(("From Name", "from@example.com"))
    .to("to@example.com")
    .subject("Subject")
    .text_body("Mail body")
    .into_message()?;

// Send the message using the implementation-agnostic `dyn DynMailer`.

mailer.send_mail(message).await?;
