ppmd-rust

Changed

• Re-licensed this crate under CC0-1.0 and MIT-0.
• There are no functional changes between 1.3 and 1.4.

Added

• Added "get_ref/get_mut" to all decoder and encoder to geta access to the inner reader / writer. By roblabla (#10)

Added

• Add an unstable-tagged-offsets unstable feature used to validate the proper function of the implementation. It is not activated as a general safety feature, since it would reduce the maximal allowed memory size and in such break compatibility with existing data.

Added

• Auto traits Send and Sync are implemented for the decoder and encoder.

Fixed

• No functional changes
• Fixed links in cargo to fix broken link in crates.io

Fixed

• Fixed errors in the ported code that created different PPMd code for both PPMd7 and PPMd7: (https://github.com/hasenbanck/ppmd-rust/issues/3)

Added

• Added bigger test corpus to verify implementation.

Added

• Added a finish() method on the encoders, so that finishing the encoding process is more straightforward.
• Allow the encoding of an end marker into the compressed data to properly support cases, where the uncompressed data size if not known at decompression time.

Updated

• Ported the C code for PPMd8 to Rust (as used in the ZIP archive format).
• Lowered MSRV to 1.82

Updated

• Ported the C code for PPMd7 to Rust (as used in the 7z archive format).

Added

• Provided a safe Rust abstraction over the 7zip PPMd C library
