class BlobCompressor
Defined at line 28 of file ../../src/storage/blobfs/compression/blob_compressor.h
A BlobCompressor is used to compress a blob transparently before it is written back to disk. This
object owns the compression buffer, and abstracts away the differences between compression
algorithms.
Public Methods
std::optional<BlobCompressor> Create (CompressionSettings settings, size_t uncompressed_blob_size)Initializes a compression object given the requested |settings| and input
|uncompressed_blob_size|.
