Trait Implementations

impl AsyncRead for DownloadTaskReader

fn poll_read( self: Pin<&mut Self>, cx: &mut Context<'_>, buffer: &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, Error>>

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

impl Display for DownloadTaskReader

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

Formats the value using the given formatter.

impl DownloadTaskSplitRead for DownloadTaskReader

fn poll_split_read( self: Pin<&mut Self>, cx: &mut Context<'_>, buffer: &mut [u8] ) -> Poll<Result<Option<(ChunkCache, Range<usize>)>>>

impl Seek for DownloadTaskReader

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

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

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

Rewind to the beginning of a stream.

fn stream_len(&mut self) -> Result<u64, Error>

🔬This is a nightly-only experimental API. (seek_stream_len)

Returns the length of this stream (in bytes).

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

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