Struct tar::Archive

pub struct Archive<R: ?Sized + Read> { /* fields omitted */ }

A top-level representation of an archive file.

This archive can have an entry added to it and it can be iterated over.

Methods

impl<R: Read> Archive<R>

fn new(obj: R) -> Archive<R>

Create a new archive with the underlying object as the reader.

fn into_inner(self) -> R

Unwrap this archive, returning the underlying object.

fn entries(&mut self) -> Result<Entries<R>>

Construct an iterator over the entries in this archive.

Note that care must be taken to consider each entry within an archive in sequence. If entries are processed out of sequence (from what the iterator returns), then the contents read for each entry may be corrupted.

fn unpack<P: AsRef<Path>>(&mut self, dst: P) -> Result<()>

Unpacks the contents tarball into the specified dst.

This function will iterate over the entire contents of this tarball, extracting each file in turn to the location specified by the entry's path name.

This operation is relatively sensitive in that it will not write files outside of the path specified by dst. Files in the archive which have a '..' in their path are skipped during the unpacking process.

Examples

use std::fs::File;
use tar::Archive;

let mut ar = Archive::new(File::open("foo.tar").unwrap());
ar.unpack("foo").unwrap();

fn set_unpack_xattrs(&mut self, unpack_xattrs: bool)

Indicate whether extended file attributes (xattrs on Unix) are preserved when unpacking this archive.

This flag is disabled by default and is currently only implemented on Unix using xattr support. This may eventually be implemented for Windows, however, if other archive implementations are found which do this as well.

fn set_preserve_permissions(&mut self, preserve: bool)

Indicate whether extended permissions (like suid on Unix) are preserved when unpacking this entry.

This flag is disabled by default and is currently only implemented on Unix.
