Struct Archive 

pub struct Archive {
    pub blocks: Vec<Block>,
    pub files: Vec<ArchiveEntry>,
    pub stream_map: StreamMap,
    pub is_solid: bool,
    /* private fields */
}

Represents a parsed 7z archive structure.

Contains metadata about the archive including files, compression blocks, and internal structure information necessary for decompression.

Fields

blocks: Vec<Block>

Compression blocks in the archive.

files: Vec<ArchiveEntry>

File and directory entries in the archive.

stream_map: StreamMap

Mapping between files, blocks, and pack streams.

is_solid: bool

Whether this is a solid archive (better compression, slower random access).

Implementations

impl Archive

pub fn open(path: impl AsRef<Path>) -> Result<Archive, Error>

Open 7z file under specified path.

pub fn open_with_password( path: impl AsRef<Path>, password: &Password, ) -> Result<Archive, Error>

Open an encrypted 7z file under specified path with password.

Parameters

• reader - the path to the 7z file
• password - archive password encoded in utf16 little endian

pub fn read<R: Read + Seek>( reader: &mut R, password: &Password, ) -> Result<Archive, Error>

Read 7z file archive info use the specified reader.

Parameters

• reader - the reader of the 7z filr archive
• password - archive password encoded in utf16 little endian

Example

use std::{
    fs::File,
    io::{Read, Seek},
};

use sevenz_rust2::*;

let mut reader = File::open("example.7z").unwrap();

let password = Password::from("the password");
let archive = Archive::read(&mut reader, &password).unwrap();

for entry in &archive.files {
    println!("{}", entry.name());
}

impl Archive

pub fn pack_pos(&self) -> u64

Returns the offset from beginning of file + SIGNATURE_HEADER_SIZE to packed streams. Used for calculating byte offsets when streaming uncompressed (COPY) content.

pub fn pack_sizes(&self) -> &[u64]

Returns the sizes of each packed stream in bytes. Used for calculating byte ranges when streaming.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Archive

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Default for Archive

fn default() -> Archive
