librust-tar+xattr-dev 0.4.20-1 (amd64 binary) in ubuntu disco

 This library does not currently handle compression, but it is abstract over all
 I/O readers and writers. Additionally, great lengths are taken to ensure that
 the entire contents are never required to be entirely resident in memory all at
 once.
 .
 This metapackage enables feature xattr for the Rust tar crate, by pulling in
 any additional dependencies needed by that feature.
