CompressionParams describes the configuration for compression.

Public Members

bool frame_checksum

bool IsValid ()

Validates the configured parameters.

size_t ComputeOutputSizeLimit (size_t len)

Returns the minimum size that a buffer must be to hold the result of compressing |len| bytes,

given the configured parameters.

size_t ChunkSizeForInputSize (size_t len, size_t target_size)

Estimates a good chunk size for the given input size.

|len| is the data input size.

|target_size| is the frame size to target. A frame size greater than or equal to this

will be returned (greater when the data is too large to support the target size.)
