Struct AutoFinishXzDecoder 

pub struct AutoFinishXzDecoder<W: Write>(/* private fields */);

A compression stream which will have compressed data written to it and will write uncompressed data to an output stream. AutoFinishXzDecoder impl Drop trait, so automatically calls XzDecoder::try_finish method when exiting the scope. However, it is not guaranteed that try_finish will complete successfully, and it is recommended to call try_finish manually if you want to ensure that the process is successful.

Implementations

impl<W: Write> AutoFinishXzDecoder<W>

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 mutating the output/input state of the stream may corrupt this object, so care must be taken when using this method.

pub fn try_finish(&mut self) -> Result<()>

Attempt to finish this output stream, writing out final chunks of data.

Note that this function can only be used once data has finished being written to the output stream. After this function is called then further calls to write may result in a panic.

Panics

Attempts to write data to this stream may result in a panic after this function is called.

pub fn finish(self) -> Result<W>

Consumes this decoder, flushing the output stream.

This will flush the underlying data stream and then return the contained writer if the flush succeeded.

Note that this function may not be suitable to call in a situation where the underlying stream is an asynchronous I/O stream. To finish a stream the try_finish method should be used instead. To re-acquire ownership of a stream it is safe to call this method after try_finish has returned Ok.

pub fn total_out(&self) -> u64

Returns the number of bytes produced by the decompressor

Note that, due to buffering, this only bears any relation to total_in() after a call to flush(). At that point, total_in() / total_out() is the compression ratio.

pub fn total_in(&self) -> u64

Returns the number of bytes consumed by the decompressor (e.g. the number of bytes written to this stream.)

Trait Implementations

impl<W: Write> Drop for AutoFinishXzDecoder<W>

fn drop(&mut self)

Executes the destructor for this type.

impl<W: Write> Write for AutoFinishXzDecoder<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.
