Struct ArchiveWriter 

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

Available on crate feature compress only.

Writes a 7z archive file.

Implementations

impl ArchiveWriter<File>

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

Available on non-WebAssembly only.

Creates a file to write a 7z archive to.

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

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

Prepares writer to write a 7z archive to.

pub fn auto_finish(self) -> AutoFinisher<Self>

Returns a wrapper around self that will finish the stream on drop.

pub fn set_content_methods( &mut self, content_methods: Vec<EncoderConfiguration>, ) -> &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: ArchiveEntry, reader: Option<R>, ) -> Result<&ArchiveEntry, Error>

Non-solid compression - Adds an archive entry with data from reader.

Example

use std::{fs::File, path::Path};

use sevenz_rust2::*;
let mut sz = ArchiveWriter::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(
        ArchiveEntry::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<ArchiveEntry>, reader: Vec<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.

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

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

Available on crate feature util and non-WebAssembly only.

Adds a source path to the compression builder with a filter function using solid compression.

The filter function allows selective inclusion of files based on their paths. Files are compressed using solid compression for better compression ratios.

Arguments

• path - Path to add to the compression
• filter - Function that returns true for paths that should be included

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

Available on crate feature util and non-WebAssembly only.

Adds a source path to the compression builder with a filter function using non-solid compression.

Non-solid compression allows individual file extraction without decompressing the entire archive, but typically results in larger archive sizes compared to solid compression.

Arguments

• path - Path to add to the compression
• filter - Function that returns true for paths that should be included
