Struct Write

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

Available on crate feature zlib only.

A utility to zlib compress anything that is written via its Write implementation.

Be sure to call flush() when done to finalize the deflate stream.

Implementations

impl<W> Write<W>

where W: Write,

pub fn new(inner: W) -> Write<W>

Create a new instance writing compressed bytes to inner.

pub fn reset(&mut self)

Reset the compressor, starting a new compression stream.

That way multiple streams can be written to the same inner writer.

pub fn into_inner(self) -> W

Consume self and return the inner writer.

Trait Implementations

impl<W> Clone for Write<W>

where W: Clone,

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<W: Write> Write for Write<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, fmt: 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.
