Struct sevenz_rust::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] compress all files in [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 contents. The default is LZMA2. And currently only support LZMA2

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

Whether to enable encrypt-header Default’s true

pub fn create_archive_entry( path: impl AsRef<Path>, entry_name: String ) -> SevenZArchiveEntry

👎Deprecated

Create an archive entry using the file in path and entry_name provided. #deprecated use SevenZArchiveEntry::from_path instead

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

Examples

use sevenz_rust::*;
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 pack [entries] into one pack

Panics

Panics if entries’s length not equals to reader.reader_len()

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

Finishes the compression.
