SendSmtpCommand

io_smtp::send

Struct SendSmtpCommand 

Source 
pub struct SendSmtpCommand<Cmd> { /* private fields */ }
Expand description

I/O-free coroutine sending one SMTP command and parsing its reply. Cmd: Into<Vec<u8>> is satisfied by every Smtp*Command struct in this crate.

Implementations§

Source§

impl<Cmd: Into<Vec<u8>>> SendSmtpCommand<Cmd>

Source

pub fn new(cmd: Cmd) -> Self

Trait Implementations§

Source§

impl<Cmd> SmtpCoroutine for SendSmtpCommand<Cmd>

Source§

type Yield = SmtpYield

Per-step value.
Source§

type Return = Result<SendSmtpCommandOk, SendSmtpCommandError>

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

fn resume( &mut self, arg: 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.
