    #可执行 API 示例

    增加 STAT/LIST 的类型化响应读取和重复编号拒绝。这些例子调用公开 API，并随 moon test 执行。

    ///|
    test "typed STAT and LIST reply consumers" {
      let s = @pop3.Session::new()
      ignore(s.feed(b"+OK\r\n"))
      ignore(s.issue(@pop3.User("u")))
      ignore(s.feed(b"+OK\r\n"))
      ignore(s.issue(@pop3.Pass("p")))
      ignore(s.feed(b"+OK\r\n"))
      ignore(s.issue(@pop3.Stat))
      let r = s.feed(b"+OK 2 300\r\n")
      assert_eq(r[0].stat(), (2, 300))
      ignore(s.issue(@pop3.List(None)))
      let r = s.feed(b"+OK list\r\n1 100\r\n2 200\r\n.\r\n")
      assert_eq(r[0].listing(), [(1, 100), (2, 200)])
    }

    0.5 已提供 TCP/隐式 TLS/STLS、APOP/PLAIN 与 Dovecot 互通。TLS 的可信握手由 Node 宿主实现；核心状态示例见 tls_auth_test.mbt。仍缺其它 SASL、PIPELINING 和流式大邮件。

    PopError

    source
    pub suberror PopError {
      Invalid(String)
    } derive(
    Debug    )

    Command

    source
    pub(all) enum Command {
      User(String)
      Pass(String)
      Apop(String, String)
      Capa
      Stls
      Auth(String)
      Stat
      List(Int?)
      Uidl(Int?)
      Retr(Int)
      Dele(Int)
      Top(Int, Int)
      Noop
      Rset
      Quit
    } derive(Eq, 
    Debug    )

    Command::encode

    source
    fn Command::encode(self : Command) -> String raise PopError

    Phase

    source
    pub(all) enum Phase {
      Greeting
      Authorization
      TlsHandshake
      Transaction
      Closed
    } derive(Eq, 
    Debug    )

    Reply

    source
    pub struct Reply {
      ok : Bool
      message : String
      body : Bytes
      continuation : Bool
    } derive(Eq, 
    Debug    )

    Reply::listing

    source
    fn Reply::listing(self : Reply) -> Array[(Int, Int)] raise PopError

    Parse the unstuffed multiline LIST body; reject duplicate message numbers.

    Reply::stat

    source
    fn Reply::stat(self : Reply) -> (Int, Int) raise PopError

    Parse a positive STAT reply as message count and total octets.

    Session

    source
    pub struct Session {
      // private fields
    } derive(
    Debug    )

    Session::authenticate_response

    source
    fn Session::authenticate_response(self : Session, response : String) -> String raise PopError

    Session::feed

    source
    fn Session::feed(self : Session, input : Bytes) -> Array[Reply] raise PopError

    Session::finish

    source
    fn Session::finish(self : Session) -> Unit raise PopError

    Session::issue

    source
    fn Session::issue(self : Session, command : Command) -> String raise PopError

    Session::new

    source
    fn Session::new() -> Session

    Session::phase

    source
    fn Session::phase(self : Session) -> Phase

    Session::tls_established

    source
    fn Session::tls_established(self : Session) -> Unit raise PopError

    Called by the transport only after a verified TLS handshake, never on STLS +OK alone.
