Enum IpcRead 

#[non_exhaustive]
pub enum IpcRead {
    File(BufReader<File>),
    Bytes(Cursor<IpcBytes>),
}

Async read implementer for IpcReadHandle::read

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

File(BufReader<File>)

Buffered reader from file.

Bytes(Cursor<IpcBytes>)

Bytes.

Implementations

impl IpcRead

pub async fn read_to_bytes(&mut self) -> Result<IpcBytes, Error>

Read all bytes until EOF to a new IpcBytes.

If the position is at 0 and is already Bytes returns it.

pub async fn remaining_len(&mut self) -> Result<u64, Error>

Remaining bytes length.

Trait Implementations

impl AsyncBufRead for IpcRead

fn poll_fill_buf( self: Pin<&mut IpcRead>, 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 IpcRead>, 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 AsyncRead for IpcRead

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

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

impl AsyncSeek for IpcRead

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

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

impl Debug for IpcRead

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

Formats the value using the given formatter.
