Struct SmtpMessageSend 

pub struct SmtpMessageSend { /* private fields */ }

Available on crate feature smtp only.

I/O-free coroutine running the RFC 5321 mail transaction over an already authenticated stream.

Implementations

impl SmtpMessageSend

pub fn new( raw: Vec<u8>, override_reverse_path: Option<&str>, ) -> Result<Self, SmtpMessageSendError>

override_reverse_path (e.g. from SmtpClientStd::default_reverse_path) takes precedence over the message’s From: header.

Trait Implementations

impl SmtpCoroutine for SmtpMessageSend

type Yield = SmtpYield

Per-step value.

type Return = Result<(), SmtpMessageSendError>

Terminal value; by convention Result<Output, Error>.

fn resume( &mut self, bytes: Option<&[u8]>, ) -> SmtpCoroutineState<Self::Yield, Self::Return>

Advances the coroutine one step. Pass None for the initial call or after a SmtpYield::WantsWrite; Some(data) after a SmtpYield::WantsRead; Some(&[]) to signal EOF.
