Struct ArchiveReader 

pub struct ArchiveReader<R: AsyncRead + AsyncSeek + Unpin> { /* private fields */ }

Reads a 7z archive file.

Implementations

impl ArchiveReader<Cursor<Vec<u8>>>

pub async fn open( path: impl AsRef<Path>, password: Password, ) -> Result<Self, Error>

Available on non-WebAssembly only.

Opens a 7z archive file asynchronously and creates an ArchiveReader using an in-memory buffer.

pub async fn open_from_bytes( data: Vec<u8>, password: Password, ) -> Result<Self, Error>

Available on non-WebAssembly only.

Opens a 7z archive from in-memory bytes asynchronously.

impl<R: AsyncRead + AsyncSeek + Unpin + Send> ArchiveReader<R>

pub fn from_archive(archive: Archive, source: R, password: Password) -> Self

Creates an ArchiveReader from an existing Archive instance.

This is useful when you already have a parsed archive and want to create a reader without re-parsing the archive structure.

Arguments

• archive - An existing parsed archive instance
• source - The reader providing access to the archive data
• password - Password for encrypted archives

pub fn set_thread_count(&mut self, thread_count: u32)

Sets the thread count to use when multi-threading is supported by the de-compression (currently only LZMA2 if encoded with MT support).

Defaults to std::thread::available_parallelism() if not set manually.

pub fn archive(&self) -> &Archive

Returns a reference to the underlying Archive structure.

This provides access to the archive metadata including files, blocks, and compression information.

pub async fn read_file(&mut self, name: &str) -> Result<Vec<u8>, Error>

Returns the data of a file with the given path inside the archive.

Notice

This function is very inefficient when used with solid archives, since it needs to decode all data before the actual file.

pub fn file_compression_methods( &self, file_name: &str, methods: &mut Vec<EncoderMethod>, ) -> Result<(), Error>

Get the compression method(s) used for a specific file in the archive.
