Function WithDecoderDictRaw

zstd/decoder_options.go:131–142

WithDecoderDictRaw registers a dictionary that may be used by the decoder. The slice content can be arbitrary data. Can be changed with ResetWithOptions.

(id uint32, content []byte)

// The slice content can be arbitrary data.
// Can be changed with ResetWithOptions.
func WithDecoderDictRaw(id uint32, content []byte) DOption {
	return func(o *decoderOptions) error {
		if bits.UintSize > 32 && uint(len(content)) > dictMaxLength {
			return fmt.Errorf("dictionary of size %d > 2GiB too large", len(content))
		}
		if o.dicts == nil {
			o.dicts = make(map[uint32]*dict)
		}
		o.dicts[id] = &dict{id: id, content: content, offsets: [3]int{1, 4, 8}}
		return nil
	}
}

// WithDecoderMaxWindow allows to set a maximum window size for decodes.
// This allows rejecting packets that will cause big memory usage.
