Implementations§

source§

impl SmtpClient

source

pub async fn new<A: ToSocketAddrs + ToString + Clone>( addr: A, timeouts: SmtpClientTimeouts ) -> Result<Self>

source

pub fn with_stream<S: AsyncReadAndWrite + 'static, H: AsRef<str>>( stream: S, peer_hostname: H, timeouts: SmtpClientTimeouts ) -> Self

source

pub fn timeouts(&self) -> &SmtpClientTimeouts

source

pub async fn read_response( &mut self, command: Option<&Command>, timeout_duration: Duration ) -> Result<Response, ClientError>

source

pub async fn send_command( &mut self, command: &Command ) -> Result<Response, ClientError>

source

pub async fn pipeline_commands( &mut self, commands: Vec<Command> ) -> Vec<Result<Response, ClientError>>

Issue a series of commands, and return the responses to those commands.

If the server advertised the RFC 2920 PIPELINING extension, the commands are written one after the other before waiting to read any data, resulting in lower overall latency due to round-trip-times.

If PIPELINING is not available, each command is written and the response read before attempting to write the next command.

The number of returned responses may be smaller than the number of requested commands if there is an issue with the network connection.

source

pub async fn ehlo( &mut self, ehlo_name: &str ) -> Result<&HashMap<String, EsmtpCapability>, ClientError>

source

pub async fn auth_plain( &mut self, username: &str, password: Option<&str> ) -> Result<(), ClientError>

source

pub async fn starttls( &mut self, options: TlsOptions ) -> Result<TlsStatus, ClientError>

Attempt TLS handshake. Returns Err for IO errors. On completion, return an option that will be:

  • Some(handshake_error) - if the handshake failed
  • None - if the handshake succeeded
source

pub async fn send_mail<B: AsRef<[u8]>, SENDER: Into<ReversePath>, RECIP: Into<ForwardPath>>( &mut self, sender: SENDER, recipient: RECIP, data: B ) -> Result<Response, ClientError>
