This crate provides a simple interface to liblzma. LZMA is more commonly known
as XZ or 7zip, (as in, files with the .xz or .7z file extension). LZMA
compression is fast and aggressive, compressing better than bzip2. liblzma
implements the XZ variant, so it can read and write .xz files/streams.
Two interfaces are provided. LzmaReader/LzmaWriter are generic Readers and
Writers that can be composed with other Read/Write interfaces. For example,
wrap them around a File and you can write data to a file while compressing it
on the fly, or stream in an xz file from disk.
compress/decompress are easy to use functions for simple use cases.
See the documentation for details on usage.
