Struct Ppmd7Encoder 

pub struct Ppmd7Encoder<W: Write> { /* private fields */ }

An encoder to compress data using PPMd7 (PPMdH) with the 7z range coder.

Implementations

impl<W: Write> Ppmd7Encoder<W>

pub fn new(writer: W, order: u32, mem_size: u32) -> Result<Self>

Creates a new Ppmd7Encoder which provides a writer over the compressed data.

The given order must be between PPMD7_MIN_ORDER and PPMD7_MAX_ORDER (inclusive). The given mem_size must be between PPMD7_MIN_MEM_SIZE and PPMD7_MAX_MEM_SIZE (inclusive).

pub fn get_ref(&self) -> &W

Gets a reference to the underlying writer.

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

Gets 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 into_inner(self) -> W

Returns the inner writer.

pub fn finish(self, with_end_marker: bool) -> Result<W>

Finishes the encoding process.

Adds an end marker to the data if with_end_marker is set to true.

Trait Implementations

impl<W: Write> Write for Ppmd7Encoder<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.
