Trait Implementations

impl<P> AsyncBufRead for Pin<P>where P: DerefMut + Unpin, <P as Deref>::Target: AsyncBufRead,

fn poll_fill_buf( self: Pin<&mut Pin<P>>, cx: &mut Context<'_> ) -> Poll<Result<&[u8], Error>>

Attempt to return the contents of the internal buffer, filling it with more data from the inner reader if it is empty.

fn consume(self: Pin<&mut Pin<P>>, amt: usize)

Tells this buffer that amt bytes have been consumed from the buffer, so they should no longer be returned in calls to poll_read.

impl<P> AsyncRead for Pin<P>where P: DerefMut + Unpin, <P as Deref>::Target: AsyncRead,

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

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

impl<P> AsyncSeek for Pin<P>where P: DerefMut + Unpin, <P as Deref>::Target: AsyncSeek,

fn poll_seek( self: Pin<&mut Pin<P>>, cx: &mut Context<'_>, pos: SeekFrom ) -> Poll<Result<u64, Error>>

Attempt to seek to an offset, in bytes, in a stream.

impl<P> AsyncWrite for Pin<P>where P: DerefMut + Unpin, <P as Deref>::Target: AsyncWrite,

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

Attempt to write bytes from bufs into the object using vectored IO operations.

fn poll_flush( self: Pin<&mut Pin<P>>, cx: &mut Context<'_> ) -> Poll<Result<(), Error>>

Attempt to flush the object, ensuring that any buffered data reach their destination.

fn poll_close( self: Pin<&mut Pin<P>>, cx: &mut Context<'_> ) -> Poll<Result<(), Error>>

Attempt to close the object.

impl<P> Deref for Pin<P>where P: Deref,

type Target = <P as Deref>::Target

The resulting type after dereferencing.

fn deref(&self) -> &<P as Deref>::Target

Dereferences the value.

impl<P> FusedFuture for Pin<P>where P: DerefMut + Unpin, <P as Deref>::Target: FusedFuture,

fn is_terminated(&self) -> bool

Returns true if the underlying future should no longer be polled.

impl<P> FusedStream for Pin<P>where P: DerefMut + Unpin, <P as Deref>::Target: FusedStream,

fn is_terminated(&self) -> bool

Returns true if the stream should no longer be polled.

impl<P> Stream for Pin<P>where P: DerefMut + Unpin, <P as Deref>::Target: Stream,

type Item = <<P as Deref>::Target as Stream>::Item

Values yielded by the stream.

fn poll_next( self: Pin<&mut Pin<P>>, cx: &mut Context<'_> ) -> Poll<Option<<Pin<P> as Stream>::Item>>

Attempt to pull out the next value of this stream, registering the current task for wakeup if the value is not yet available, and returning None if the stream is exhausted.

fn size_hint(&self) -> (usize, Option<usize>)

Returns the bounds on the remaining length of the stream.

impl<'a, T, F> UnsafeFutureObj<'a, T> for Pin<Box<F, Global>>where F: Future<Output = T> + 'a,

fn into_raw(self) -> *mut dyn Future<Output = T> + 'a

Convert an owned instance into a (conceptually owned) fat pointer.

unsafe fn drop(ptr: *mut dyn Future<Output = T> + 'a)

Drops the future represented by the given fat pointer.
