Arithmetic Coding

A symbolic arithmetic coding library.

Extending this library is as simple as implementing the Model trait for your own type, and then plugging it in the provided Encoder/Decoder. Supports both fixed-length and variable-length encoding, as well as both adaptive and non-adaptive models.

Take a look at the API docs or the examples.
