Struct Chain

pub struct Chain<R1, R2> { /* private fields */ }

Reader for the AsyncReadExt::chain() method.

Implementations

impl<R1, R2> Chain<R1, R2>

pub fn get_ref(&self) -> (&R1, &R2)

Gets references to the underlying readers.

Examples

use futures_lite::io::{AsyncReadExt, Cursor};

let r1 = Cursor::new(b"hello");
let r2 = Cursor::new(b"world");

let reader = r1.chain(r2);
let (r1, r2) = reader.get_ref();

pub fn get_mut(&mut self) -> (&mut R1, &mut R2)

Gets mutable references to the underlying readers.

Examples

use futures_lite::io::{AsyncReadExt, Cursor};

let r1 = Cursor::new(b"hello");
let r2 = Cursor::new(b"world");

let mut reader = r1.chain(r2);
let (r1, r2) = reader.get_mut();

pub fn into_inner(self) -> (R1, R2)

Unwraps the adapter, returning the underlying readers.

Examples

use futures_lite::io::{AsyncReadExt, Cursor};

let r1 = Cursor::new(b"hello");
let r2 = Cursor::new(b"world");

let reader = r1.chain(r2);
let (r1, r2) = reader.into_inner();

Trait Implementations

impl<R1, R2> AsyncBufRead for Chain<R1, R2>

where R1: AsyncBufRead, R2: AsyncBufRead,

fn poll_fill_buf( self: Pin<&mut Chain<R1, R2>>, 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 Chain<R1, R2>>, 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<R1, R2> AsyncRead for Chain<R1, R2>

where R1: AsyncRead, R2: AsyncRead,

fn poll_read( self: Pin<&mut Chain<R1, R2>>, 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 Chain<R1, R2>>, cx: &mut Context<'_>, bufs: &mut [IoSliceMut<'_>], ) -> Poll<Result<usize, Error>>

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

impl<R1, R2> Debug for Chain<R1, R2>

where R1: Debug, R2: Debug,

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

Formats the value using the given formatter.

impl<'__pin, R1, R2> Unpin for Chain<R1, R2>

where <PinnedFieldsOfHelperStruct<__Origin<'__pin, R1, R2>> as PinnedFieldsOfHelperTrait>::Actual: Unpin,
