Struct SevenZReader

pub struct SevenZReader<R: Read + Seek> { /* private fields */ }

Reads a 7z file.

Implementations

impl SevenZReader<File>

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

Opens a 7z archive file at the given path and creates a SevenZReader to read it.

impl<R: Read + Seek> SevenZReader<R>

pub fn new(source: R, password: Password) -> Result<Self, Error>

Creates a SevenZReader to read a 7z archive file from the given source reader.

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

pub fn archive(&self) -> &Archive

pub fn for_each_entries<F: FnMut(&SevenZArchiveEntry, &mut dyn Read) -> Result<bool, Error>>( &mut self, each: F, ) -> Result<(), Error>

Takes a closure to decode each files in the archive.

Attention about solid archive: When decoding a solid archive, the data to be decompressed depends on the data in front of it, you cannot simply skip the previous data and only decompress the data in the back.

pub 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<SevenZMethod>, ) -> Result<(), Error>

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