Types

type Zstd

type Zstd struct {

	// Set compression parameters according to pre-defined compression level table.
	// Note that exact compression parameters are dynamically determined,
	// depending on both compression level and source content size (when known).
	// Value 0 means default, and default level is 3.
	// Setting a level does not automatically set all other compression parameters
	// to default. Setting this will however eventually dynamically impact the compression
	// parameters which have not been manually set. The manually set
	// ones will 'stick'.
	CompressionLevel *wrapperspb.UInt32Value `protobuf:"bytes,1,opt,name=compression_level,json=compressionLevel,proto3" json:"compression_level,omitempty"`
	// A 32-bits checksum of content is written at end of frame. If not set, defaults to false.
	EnableChecksum bool `protobuf:"varint,2,opt,name=enable_checksum,json=enableChecksum,proto3" json:"enable_checksum,omitempty"`
	// The higher the value of selected strategy, the more complex it is,
	// resulting in stronger and slower compression.
	// Special: value 0 means "use default strategy".
	Strategy Zstd_Strategy `` /* 137-byte string literal not displayed */
	// A dictionary for compression. Zstd offers dictionary compression, which greatly improves
	// efficiency on small files and messages. Each dictionary will be generated with a dictionary ID
	// that can be used to search the same dictionary during decompression.
	// Please refer to `zstd manual <https://github.com/facebook/zstd/blob/dev/programs/zstd.1.md#dictionary-builder>`_
	// to train a specific dictionary for compression.
	Dictionary *v3.DataSource `protobuf:"bytes,4,opt,name=dictionary,proto3" json:"dictionary,omitempty"`
	// Value for compressor's next output buffer. If not set, defaults to 4096.
	ChunkSize *wrapperspb.UInt32Value `protobuf:"bytes,5,opt,name=chunk_size,json=chunkSize,proto3" json:"chunk_size,omitempty"`
	// contains filtered or unexported fields
}
