Implementations

impl<W: Write> ProgressWriter<W>

pub fn new(inner: W) -> Self

Create a new progress writer

pub fn with_total_bytes(self, total: u64) -> Self

Set total bytes for progress calculation

pub fn with_progresscallback(self, callback: ProgressCallback) -> Self

Set progress callback

pub fn with_progress_interval(self, interval: u64) -> Self

Set progress reporting interval

pub fn progress(&self) -> StreamProgress

Get current progress

Trait Implementations

impl<W: Write> Write for ProgressWriter<W>

fn write(&mut self, buf: &[u8]) -> Result<usize>

Writes a buffer into this writer, returning how many bytes were written.

fn flush(&mut self) -> Result<()>

Flushes this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write_vectored(&mut self, bufs: &[IoSlice<'_>]) -> Result<usize, Error>

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

fn is_write_vectored(&self) -> bool

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

Determines if this Writer has an efficient write_vectored implementation.

fn write_all(&mut self, buf: &[u8]) -> Result<(), Error>

Attempts to write an entire buffer into this writer.

fn write_all_vectored(&mut self, bufs: &mut [IoSlice<'_>]) -> Result<(), Error>

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

Attempts to write multiple buffers into this writer.

fn write_fmt(&mut self, args: Arguments<'_>) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

fn by_ref(&mut self) -> &mut Self

where Self: Sized,

Creates a “by reference” adapter for this instance of Write.
