//! *pxar* Implementation //! //! This code implements a slightly modified version of the *catar* //! format used in the [casync](https://github.com/systemd/casync) //! toolkit (we are not 100% binary compatible). It is a file archive //! format defined by 'Lennart Poettering', specially defined for //! efficent deduplication. //! Every archive contains items in the following order: //! * ENTRY -- containing general stat() data and related bits //! * USER -- user name as text, if enabled //! * GROUP -- group name as text, if enabled //! * XATTR -- one extended attribute //! * ... -- more of these when there are multiple defined //! * ACL_USER -- one USER ACL entry //! * ... -- more of these when there are multiple defined //! * ACL_GROUP -- one GROUP ACL entry //! * ... -- more of these when there are multiple defined //! * ACL_GROUP_OBJ -- The ACL_GROUP_OBJ //! * ACL_DEFAULT -- The various default ACL fields if there's one defined //! * ACL_DEFAULT_USER -- one USER ACL entry //! * ... -- more of these when multiple are defined //! * ACL_DEFAULT_GROUP -- one GROUP ACL entry //! * ... -- more of these when multiple are defined //! * FCAPS -- file capability in Linux disk format //! * QUOTA_PROJECT_ID -- the ext4/xfs quota project ID //! * PAYLOAD -- file contents, if it is one //! * SYMLINK -- symlink target, if it is one //! * DEVICE -- device major/minor, if it is a block/char device //! //! If we are serializing a directory, then this is followed by: //! //! * FILENAME -- name of the first directory entry (strictly ordered!) //! * -- serialization of the first directory entry's metadata and contents, //! following the exact same archive format //! * FILENAME -- name of the second directory entry (strictly ordered!) //! * -- serialization of the second directory entry //! * ... //! * GOODBYE -- lookup table at the end of a list of directory entries mod binary_search_tree; mod format_definition; pub use format_definition::*; mod encoder; pub use encoder::*; mod sequential_decoder; pub use sequential_decoder::*;
