Struct zstd::stream::write::AutoFlushDecoder

pub struct AutoFlushDecoder<'a, W: Write, F: FnMut(Result<()>) = Box<dyn Send + FnMut(Result<()>)>> { /* private fields */ }

A wrapper around a Decoder<W> that flushes the stream on drop.

This can be created by the auto_flush() method on the Decoder.

Implementations

impl<'a, W: Write, F: FnMut(Result<()>)> AutoFlushDecoder<'a, W, F>

pub fn get_ref(&self) -> &W

Acquires a reference to the underlying writer.

pub fn get_mut(&mut self) -> &mut W

Acquires a mutable reference to the underlying writer.

Note that mutation of the writer may result in surprising results if this decoder is continued to be used.

Mostly used for testing purposes.

Trait Implementations

impl<W, F> Drop for AutoFlushDecoder<'_, W, F>

where W: Write, F: FnMut(Result<()>),

fn drop(&mut self)

Executes the destructor for this type.

impl<W: Write, F: FnMut(Result<()>)> Write for AutoFlushDecoder<'_, W, F>

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

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

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

Flush 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.
