Function WithDecoderDicts

zstd/decoder_options.go:112–126

WithDecoderDicts allows to register one or more dictionaries for the decoder. Each slice in dict must be in the [dictionary format] produced by "zstd --train" from the Zstandard reference implementation. If several dictionaries with the same ID are provided, the last one will be used. Can be chang

(dicts ...[]byte)

//
// [dictionary format]: https://github.com/facebook/zstd/blob/dev/doc/zstd_compression_format.md#dictionary-format
func WithDecoderDicts(dicts ...[]byte) DOption {
	return func(o *decoderOptions) error {
		if o.dicts == nil {
			o.dicts = make(map[uint32]*dict)
		}
		for _, b := range dicts {
			d, err := loadDict(b)
			if err != nil {
				return err
			}
			o.dicts[d.id] = d
		}
		return nil
	}
}

// WithDecoderDictRaw registers a dictionary that may be used by the decoder.
// The slice content can be arbitrary data.
