Struct FromFutures 

pub struct FromFutures<T: ?Sized> { /* private fields */ }

Available on crate feature futures-03 only.

Adapter from futures::io traits.

Implementations

impl<T> FromFutures<T>

pub fn new(inner: T) -> Self

Create a new adapter.

pub fn into_inner(self) -> T

Consume the adapter, returning the inner object.

impl<T: ?Sized> FromFutures<T>

pub fn inner(&self) -> &T

Borrow the inner object.

pub fn inner_mut(&mut self) -> &mut T

Mutably borrow the inner object.

Trait Implementations

impl<T: AsyncBufRead + Unpin + ?Sized> BufRead for FromFutures<T>

async fn fill_buf(&mut self) -> Result<&[u8], Self::Error>

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

fn consume(&mut self, amt: usize)

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

impl<T: Clone + ?Sized> Clone for FromFutures<T>

fn clone(&self) -> FromFutures<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: ?Sized> ErrorType for FromFutures<T>

type Error = Error

Error type of all the IO operations on this type.

impl<T: AsyncRead + Unpin + ?Sized> Read for FromFutures<T>

async fn read(&mut self, buf: &mut [u8]) -> Result<usize, Self::Error>

Read some bytes from this source into the specified buffer, returning how many bytes were read.

async fn read_exact( &mut self, buf: &mut [u8], ) -> Result<(), ReadExactError<Self::Error>>

Read the exact number of bytes required to fill buf.

impl<T: AsyncSeek + Unpin + ?Sized> Seek for FromFutures<T>

async fn seek(&mut self, pos: SeekFrom) -> Result<u64, Self::Error>

Seek to an offset, in bytes, in a stream.

async fn rewind(&mut self) -> Result<(), Self::Error>

Rewind to the beginning of a stream.

async fn stream_position(&mut self) -> Result<u64, Self::Error>

Returns the current seek position from the start of the stream.

impl<T: AsyncWrite + Unpin + ?Sized> Write for FromFutures<T>

async fn write(&mut self, buf: &[u8]) -> Result<usize, Self::Error>

Write a buffer into this writer, returning how many bytes were written.

async fn flush(&mut self) -> Result<(), Self::Error>

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

async fn write_all(&mut self, buf: &[u8]) -> Result<(), Self::Error>

Write an entire buffer into this writer.
