Struct Mailer 

pub struct Mailer { /* private fields */ }

A configured, ready-to-use sender.

Built once at boot and shared by every worker: the HTTP client pools its connections and the SMTP transport pools its sessions, so a per-request Mailer would be strictly worse and is not offered.

Implementations

impl Mailer

pub fn from_config(config: &EmailConfig) -> Result<Option<Mailer>, EmailError>

Build the sender an app’s [email] section describes.

Ok(None) means the app doesn’t send mail (provider = "none", the default) — not an error, just nothing to build. Err means it asked for a provider and the request can’t be honoured, which is worth failing the boot over: the alternative is discovering it at the first send.

pub fn provider(&self) -> Provider

Which provider this mailer sends through.

pub async fn send(&self, message: &Message) -> Result<Sent, EmailError>

Send one message.
