Struct SmtpClient 

pub struct SmtpClient { /* private fields */ }

SMTP client — wraps lettre for sending emails.

Thread-safe via Arc<SmtpTransport>. Created once during kernel init from [email] config and stored in EmailApi.

Implementations

impl SmtpClient

pub fn from_config(config: &EmailConfig, password: &str) -> Result<Self>

Build an SmtpClient from config and credentials.

password is the SMTP auth password (app password for Gmail). It is never stored beyond the lettre transport internals.

pub async fn send( &self, _to: &str, subject: &str, html: &str, text: Option<&str>, ) -> Result<SendReceipt>

Send an email.

In v1, to is ignored — always sends to default_to (the user’s own email). If text is None, a minimal plain-text fallback is generated from the subject.

pub async fn test_connection(&self) -> Result<()>

Test the SMTP connection by sending a simple test email.

pub fn from_addr(&self) -> &str

The “from” address (user’s own email).

pub fn default_to(&self) -> &str

The default “to” address (user’s own email, same as from in v1).

fn fmt(&self, f: &mut Formatter<'_>) -> Result
