-/// This struct provides the functionality to compress and decompress data using
-/// the GZip algorithm. It implements the `CompressionEngine` trait for integration
-/// with the compression service.
-///
-/// # Examples
-///
-/// ```rust
-/// let engine = keep::compression_engine::get_compression_engine(keep::compression_engine::CompressionType::GZip)
-///     .expect("Failed to get GZip engine");
-/// assert!(engine.is_supported());
