Struct MaybeTlsStream 

pub struct MaybeTlsStream<S>(/* private fields */);

Available on crate feature tls only.

A futures-based stream that can be either plain TCP or TLS-encrypted.

Implementations

impl<S> MaybeTlsStream<S>

pub fn new_plain(stream: S) -> MaybeTlsStream<S>

Create an unencrypted stream.

pub fn new_tls(stream: TlsStream<S>) -> MaybeTlsStream<S>

Create a TLS-encrypted stream.

pub fn is_tls(&self) -> bool

Whether the stream is TLS-encrypted.

impl<S> MaybeTlsStream<S>

where S: AsyncRead + AsyncWrite + Unpin,

pub fn negotiated_alpn(&self) -> Option<Cow<'_, [u8]>>

Returns the negotiated ALPN protocol.

Trait Implementations

impl<S> AsyncRead for MaybeTlsStream<S>

where S: AsyncRead + AsyncWrite + Unpin,

fn poll_read( self: Pin<&mut MaybeTlsStream<S>>, cx: &mut Context<'_>, buf: &mut [u8], ) -> Poll<Result<usize, Error>>

Attempt to read from the AsyncRead into buf.

fn poll_read_vectored( self: Pin<&mut Self>, cx: &mut Context<'_>, bufs: &mut [IoSliceMut<'_>], ) -> Poll<Result<usize, Error>>

Attempt to read from the AsyncRead into bufs using vectored IO operations.

impl<S> AsyncWrite for MaybeTlsStream<S>

where S: AsyncRead + AsyncWrite + Unpin,

fn poll_write( self: Pin<&mut MaybeTlsStream<S>>, cx: &mut Context<'_>, buf: &[u8], ) -> Poll<Result<usize, Error>>

Attempt to write bytes from buf into the object.

fn poll_write_vectored( self: Pin<&mut MaybeTlsStream<S>>, cx: &mut Context<'_>, bufs: &[IoSlice<'_>], ) -> Poll<Result<usize, Error>>

impl<S> Debug for MaybeTlsStream<S>

where S: Debug,

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

Formats the value using the given formatter.

impl<S> IntoMaybeTlsStream<S> for MaybeTlsStream<PollFd<S>>

where S: AsFd,

fn into_maybe_tls_stream(self) -> Result<MaybeTlsStream<PollFd<S>>, Error>

Convert this stream into a MaybeTlsStream.
