class Lz4Decompressor

Defined at line 23 of file ../../src/storage/volume_image/utils/lz4_decompressor.h

This class provides an implementation of |Decompressor| backed by LZ4 Decompression algorithm.

This class is move construcable only.

static const uint64_t kDecompressionBufferSize

fpromise::result<Lz4Decompressor, std::string> Create (const CompressionOptions & options, uint64_t decompression_buffer_size)

Returns a |Lz4Decompressor| on success.

On failure, returns a string describing the error.

fpromise::result<void, std::string> Prepare (Handler handler)

Returns |fpromise::ok| on success. Setting |handler| for consuming symbols emitted during

decompression.

On failure, returns a string decribing the error condition.

fpromise::result<DecompressResult, std::string> Decompress (std::span<const uint8_t> compressed_data)

Returns |fpromise::ok| on success. When data has been fully decompressed, will return |true|,

otherwise will return |false|.

On failure, returns a string decribing the error condition.

fpromise::result<void, std::string> Finalize ()

Returns |fpromise::ok| on success. At this point all remaining symbols for the decompressed

representation will be emitted.

On failure, returns a string describing the error condition.
