Function WithDecoderMaxMemory

zstd/decoder_options.go:90–101

WithDecoderMaxMemory allows to set a maximum decoded size for in-memory non-streaming operations or maximum window size for streaming operations. This can be used to control memory usage of potentially hostile content. Maximum is 1 << 63 bytes. Default is 64GiB. Can be changed with ResetWithOptions.

(n uint64)

// Maximum is 1 << 63 bytes. Default is 64GiB.
// Can be changed with ResetWithOptions.
func WithDecoderMaxMemory(n uint64) DOption {
	return func(o *decoderOptions) error {
		if n == 0 {
			return errors.New("WithDecoderMaxMemory must be at least 1")
		}
		if n > 1<<63 {
			return errors.New("WithDecoderMaxmemory must be less than 1 << 63")
		}
		o.maxDecodedSize = n
		return nil
	}
}

// WithDecoderDicts allows to register one or more dictionaries for the decoder.
