This crate provides low-level bindings to [Adaptive Entropy Coding library (libaec)](https://gitlab.dkrz.de/k202009/libaec).

The description of libaec is as follows:

> Libaec provides fast lossless compression of 1 up to 32 bit wide
> signed or unsigned integers (samples). The library achieves best
> results for low entropy data as often encountered in space imaging
> instrument data or numerical model output from weather or climate
> simulations. While floating point representations are not directly
> supported, they can also be efficiently coded by grouping exponents
> and mantissa.
>
> ## Scope
>
> Libaec implements extended
> [Golomb-Rice](http://en.wikipedia.org/wiki/Golomb_coding) coding as
> defined in the CCSDS recommended standard [121.0-B-3][1]. The library
> covers the adaptive entropy coder and the preprocessor discussed in
> sections 1 to 5.2.6 of the [standard][1].
