Crate sevenz_rust2 

This project is a 7z compressor/decompressor written in pure Rust.

This is a fork of the original, unmaintained sevenz-rust crate to continue the development and maintenance.

Modules

encoder_optionscompress

Encoding options when compressing.

Structs

Archive

Represents a parsed 7z archive structure.

ArchiveEntry

Represents a single file or directory entry within a 7z archive.

ArchiveReader

Reads a 7z archive file.

ArchiveWritercompress

Writes a 7z archive file.

AutoFinisher

A wrapper around a writer that finishes the stream on drop.

Block

Represents a compression block.

BlockDecoder

Decoder for a specific block within a 7z archive.

Coder

Represents a single coder within a compression block.

EncoderConfigurationcompress

Configuration for encoding methods when compressing data.

EncoderMethod

Encoder method that can be chained (filter, compression and encryption).

NtTime

A type that represents a Windows file time and is used in the 7z archive format.

OrderedCoderIter

Iterator that yields coders in their processing order within a block.

Password

A password used for password protected, encrypted files.

SourceReader

A wrapper around a reader that tracks read count and CRC32.

StreamMap

Mapping structure that correlates files, blocks, and pack streams within an archive.

Enums

Error

The error type of the crate.

Constants

SIGNATURE_HEADER_SIZE

Size of the 7z signature header in bytes (32 bytes). This is needed for calculating absolute byte offsets within the archive.
