Module zstd::dict

Train a dictionary from various sources.

A dictionary can help improve the compression of small files. The dictionary must be present during decompression, but can be shared accross multiple “similar” files.

Creating a dictionary using the zstd C library, using the zstd command-line interface, using this library, or using the train binary provided, should give the same result, and are therefore completely compatible.

To use, see Encoder::with_dictionary or Decoder::with_dictionary.
