Struct Service 

pub struct Service { /* private fields */ }

Service implements all the mandatory mail services

• IoService so it can be used with TcpServer or UnixServer.

Build it using the Builder

Implementations

impl Service

pub fn new<T, I, E, G, D>( drive: T, interpret: I, session: E, guard: G, dispatch: D, ) -> Service

where T: Drive + Sync + Send + 'static, I: Interpret + Sync + Send + 'static, E: SessionService + Sync + Send + 'static, G: MailGuard + Sync + Send + 'static, D: MailDispatch + Sync + Send + 'static,

Compose the service from parts

Trait Implementations

impl Clone for Service

fn clone(&self) -> Service

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Service

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

Formats the value using the given formatter.

impl IoService for Service

fn handle( &self, io: Result<Box<dyn MayBeTls>, Box<dyn Error + Sync + Send>>, connection: ConnectionInfo, ) -> Pin<Box<dyn Future<Output = Result<(), Box<dyn Error + Sync + Send>>> + Send>>

impl MailDispatch for Service

fn open_mail_body<'a, 's, 'f>( &'a self, session: &'s mut SmtpSession, ) -> Pin<Box<dyn Future<Output = Result<(), DispatchError>> + Send + 'f>>

where 'a: 'f, 's: 'f,

Add a mail data sink to mail transaction.

impl MailGuard for Service

fn add_recipient<'a, 's, 'f>( &'a self, session: &'s mut SmtpSession, rcpt: Recipient, ) -> Pin<Box<dyn Future<Output = AddRecipientResult> + Sync + Send + 'f>>

where 'a: 'f, 's: 'f,

Add given RCPT to the list. Here we can immediately add and further processing will stop with success. Or we can refuse and stop further processing with a failure. Last option is to return Inconclusive in which case other MailGuards will have a chance. If all MailGuards return Inconclusive, the caller should assume success and add the RCPT to the list.

fn start_mail<'a, 's, 'f>( &'a self, session: &'s mut SmtpSession, ) -> Pin<Box<dyn Future<Output = StartMailResult> + Sync + Send + 'f>>

where 'a: 'f, 's: 'f,

Open the mail transaction. Here we have the opportunity to check the sender, adjust transaction ID…

impl SessionService for Service

fn prepare_session<'a, 'i, 's, 'f>( &'a self, io: &'i mut Box<dyn MayBeTls>, state: &'s mut SmtpContext, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'f>>

where 'a: 'f, 'i: 'f, 's: 'f,
