Trait Implementations

impl<'a, St, F> AsyncRead for LogStreamProgress<St, F> where
    St: FAsyncRead,
    F: FnMut(usize), 

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

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>>

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

impl<'a, St, F> AsyncRead for LogStreamProgress<St, F> where
    St: TAsyncRead,
    F: FnMut(usize), 

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

Attempts to read from the AsyncRead into buf.

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_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<St, F> Debug for LogStreamProgress<St, F> where
    St: Debug, 

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

Formats the value using the given formatter.

impl<T, U> Unpin for LogStreamProgress<T, U> where
    T: Unpin,
    U: Unpin,
