Variants

Ehlo(Domain)

Helo(Domain)

Lhlo(Domain)

Noop(Option<String>)

Help(Option<String>)

Vrfy(Option<String>)

Expn(Option<String>)

Data

DataDot

The end-of-data terminator sent after the message body: ".\r\n".

This variant is never produced by the parser — it is constructed programmatically by SMTP client code and serialized via Command::encode when the client needs to signal the end of the DATA content stream (RFC 5321 §4.5.2).

Rset

Quit

StartTls

MailFrom

Fields

address: ReversePath

parameters: Vec<EsmtpParameter>

RcptTo

Fields

address: ForwardPath

parameters: Vec<EsmtpParameter>

Auth

Fields

sasl_mech: String

initial_response: Option<String>

XClient(Vec<XClientParameter>)

Unknown(BString)

Implementations

impl Command

pub fn parse(input: impl AsRef<[u8]>) -> Result<MaybePartialCommand, String>

pub fn encode(&self) -> BString

Re-encode the command as a single line of text ready to send on the wire, including the trailing \r\n.

The returned BString can be fed back to Command::parse to recover the original Command value (round-trip stable), with the one intentional exception that at_domain_list source routes are not re-emitted (RFC 5321 says they SHOULD NOT be generated).

pub fn client_timeout(&self, timeouts: &SmtpClientTimeouts) -> Duration

Timeout for reading the response to this command.

pub fn client_timeout_request(&self, timeouts: &SmtpClientTimeouts) -> Duration

Timeout for writing the request.

Trait Implementations

impl Clone for Command

fn clone(&self) -> Command

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Command

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

Formats the value using the given formatter.

impl PartialEq for Command

fn eq(&self, other: &Command) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Eq for Command
