Struct pwn::io::Empty

pub struct Empty { /* fields omitted */ }

An async reader which is always at EOF.

This struct is generally created by calling empty. Please see the documentation of empty() for more details.

This is an asynchronous version of std::io::empty.

Trait Implementations

impl AsyncBufRead for Empty

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

Attempts 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 Empty>, 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 AsyncRead for Empty

unsafe fn prepare_uninitialized_buffer(
    &self,
    _buf: &mut [MaybeUninit<u8>]
) -> bool

Prepares an uninitialized buffer to be safe to pass to read. Returns true if the supplied buffer was zeroed out.

fn poll_read(
    self: Pin<&mut Empty>,
    &mut Context,
    &mut [u8]
) -> Poll<Result<usize, Error>>

Attempts to read from the AsyncRead into buf.

fn poll_read_buf<B>(
    self: Pin<&mut Self>,
    cx: &mut Context,
    buf: &mut B
) -> Poll<Result<usize, Error>> where
    B: BufMut, 

Pulls some bytes from this source into the specified BufMut, returning how many bytes were read.

impl Debug for Empty

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

Formats the value using the given formatter.
