Struct SevenZWriter

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

Writes a 7z file.

Implementations

impl<W: Write + Seek> SevenZWriter<W>

pub fn push_source_path( &mut self, path: impl AsRef<Path>, filter: impl Fn(&Path) -> bool, ) -> Result<&mut Self, Error>

Solid compression - compress all files in path with multiple files in one block.

pub fn push_source_path_non_solid( &mut self, path: impl AsRef<Path>, filter: impl Fn(&Path) -> bool, ) -> Result<&mut Self, Error>

Non-solid compression - compresses all files into path with one file per block.

impl SevenZWriter<File>

pub fn create(path: impl AsRef<Path>) -> Result<Self, Error>

Creates a file to write a 7z archive to.

impl<W: Write + Seek> SevenZWriter<W>

pub fn new(writer: W) -> Result<Self, Error>

Prepares writer to write a 7z archive to.

pub fn set_content_methods( &mut self, content_methods: Vec<SevenZMethodConfiguration>, ) -> &mut Self

Sets the default compression methods to use for entry data. Default is LZMA2.

pub fn set_encrypt_header(&mut self, enabled: bool)

Whether to enable the encryption of the -header. Default is true.

pub fn push_archive_entry<R: Read>( &mut self, entry: SevenZArchiveEntry, reader: Option<R>, ) -> Result<&SevenZArchiveEntry, Error>

Adds an archive entry with data from reader.

Example

use sevenz_rust2::*;
use std::fs::File;
use std::path::Path;
let mut sz = SevenZWriter::create("path/to/dest.7z").expect("create writer ok");
let src = Path::new("path/to/source.txt");
let name = "source.txt".to_string();
let entry = sz.push_archive_entry(
              SevenZArchiveEntry::from_path(&src, name),
              Some(File::open(src).unwrap()),
          )
          .expect("ok");
let compressed_size = entry.compressed_size;
sz.finish().expect("done");

pub fn push_archive_entries<R: Read>( &mut self, entries: Vec<SevenZArchiveEntry>, reader: SeqReader<SourceReader<R>>, ) -> Result<&mut Self, Error>

Solid compression - packs entries into one pack.

Panics

• If entries’s length not equals to reader.reader_len()

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

Finishes the compression.
