Usage: blobfs-compression [--option1=value --option2 ...]
The tool will output the maximum possible compressed file size using the exact same
compression implementation in blobfs. The merkle tree used here is a non-compact merkle
tree as it contributes to a bigger size than a compact merkle tree.
选项：
--source_file=/path/to/file
The file to be compressed.
--compressed_file=/path/to/file
The compressed file output path (override if existing). Unless --type is specified, will contain compressed data with zero-padding at the end to ensure the compressed file size matches the size in stdout.
--type=TYPE
If specified, use specified type when generating the output. Supported types:
1 - Type A: zstd-chunked, default compression level
--disable_size_alignment
Do not align compressed output with block size. Incompatible with --type.
--calculate_digest=/path/to/file
Calculate the Merkle root/digest of a delivery blob (i.e. one created with --type). Other options are ignored if set.
--help
print this usage message.
--verbose
show debugging information.
