Types

type Gzip 

type Gzip struct {

	// Value from 1 to 9 that controls the amount of internal memory used by zlib. Higher values
	// use more memory, but are faster and produce better compression results. The default value is 5.
	MemoryLevel *wrapperspb.UInt32Value `protobuf:"bytes,1,opt,name=memory_level,json=memoryLevel,proto3" json:"memory_level,omitempty"`
	// A value used for selecting the zlib compression level. This setting will affect speed and
	// amount of compression applied to the content. "BEST_COMPRESSION" provides higher compression
	// at the cost of higher latency and is equal to "COMPRESSION_LEVEL_9". "BEST_SPEED" provides
	// lower compression with minimum impact on response time, the same as "COMPRESSION_LEVEL_1".
	// "DEFAULT_COMPRESSION" provides an optimal result between speed and compression. According
	// to zlib's manual this level gives the same result as "COMPRESSION_LEVEL_6".
	// This field will be set to "DEFAULT_COMPRESSION" if not specified.
	CompressionLevel Gzip_CompressionLevel `` /* 185-byte string literal not displayed */
	// A value used for selecting the zlib compression strategy which is directly related to the
	// characteristics of the content. Most of the time "DEFAULT_STRATEGY" will be the best choice,
	// which is also the default value for the parameter, though there are situations when
	// changing this parameter might produce better results. For example, run-length encoding (RLE)
	// is typically used when the content is known for having sequences which same data occurs many
	// consecutive times. For more information about each strategy, please refer to zlib manual.
	CompressionStrategy Gzip_CompressionStrategy `` /* 197-byte string literal not displayed */
	// Value from 9 to 15 that represents the base two logarithmic of the compressor's window size.
	// Larger window results in better compression at the expense of memory usage. The default is 12
	// which will produce a 4096 bytes window. For more details about this parameter, please refer to
	// zlib manual > deflateInit2.
	WindowBits *wrapperspb.UInt32Value `protobuf:"bytes,4,opt,name=window_bits,json=windowBits,proto3" json:"window_bits,omitempty"`
	// Value for Zlib's next output buffer. If not set, defaults to 4096.
	// See https://www.zlib.net/manual.html for more details. Also see
	// https://github.com/envoyproxy/envoy/issues/8448 for context on this filter's performance.
	ChunkSize *wrapperspb.UInt32Value `protobuf:"bytes,5,opt,name=chunk_size,json=chunkSize,proto3" json:"chunk_size,omitempty"`
	// contains filtered or unexported fields
}
