Struct iroh_blobs::util::io::TrackingWriter

pub struct TrackingWriter<W> { /* private fields */ }

A writer that tracks the number of bytes written

Implementations

impl<W> TrackingWriter<W>

pub fn new(inner: W) -> Self

Wrap a writer in a tracking writer

pub fn bytes_written(&self) -> u64

Get the number of bytes written

pub fn into_parts(self) -> (W, u64)

Get the inner writer

Trait Implementations

impl<W: AsyncWrite + Unpin> AsyncWrite for TrackingWriter<W>

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

Attempt to write bytes from buf into the object.

fn poll_flush(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Result<()>>

Attempts to flush the object, ensuring that any buffered data reach their destination.

fn poll_shutdown(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Result<()>>

Initiates or attempts to shut down this writer, returning success when the I/O connection has completely shut down.

fn poll_write_vectored( self: Pin<&mut Self>, cx: &mut Context<'_>, bufs: &[IoSlice<'_>] ) -> Poll<Result<usize, Error>>

Like poll_write, except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool

Determines if this writer has an efficient poll_write_vectored implementation.

impl<W: Debug> Debug for TrackingWriter<W>

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

Formats the value using the given formatter.
