Struct lzma_rust::LZMAWriter

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

Compresses into the legacy .lzma file format or into a raw LZMA stream

Examples

use std::io::Write;
use lzma_rust::{LZMA2Options, LZMAWriter};
let s = b"Hello, world!";
let mut out = Vec::new();
let mut options = LZMA2Options::with_preset(6);
options.dict_size = LZMA2Options::DICT_SIZE_DEFAULT;
let mut w = LZMAWriter::new_no_header(CountingWriter::new(&mut out), &options, false).unwrap();
w.write_all(&s).unwrap();
w.write(&[]).unwrap();

Implementations

impl<W: Write> LZMAWriter<W>

pub fn new( out: CountingWriter<W>, options: &LZMA2Options, use_header: bool, use_end_marker: bool, expected_uncompressed_size: Option<u64>, ) -> Result<LZMAWriter<W>, Error>

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

Trait Implementations

impl<W: Write> Write for LZMAWriter<W>

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.
