Tool written origintally to test the deflate, but now has functionality to compare several crates that do deflate compression/decompression.
Compare compression efficiency and speed of raw deflate encoding using the default compression level:
cargo run --release -- -c /path/to/directory/or/file/to/test
cargo run --release -- -d /path/to/directory/or/file/to/test
Additionally, the -t <type> switch, where type is either zlib or gzip can be used to compare compression/decompression with a zlib or gzip wrapper respectively.
