zlight_csv

ZLight brings the speed of Rust to Ruby's CSV parsing. Built as a native extension, it delivers up to 30x faster performance than Ruby's standard CSV library while maintaining full API compatibility. Whether you're parsing small configuration files or processing millions of rows, ZLight handles it efficiently. The streaming API enables memory-efficient processing of large datasets by reading rows one at a time, and lazy enumeration lets you stop early without wasting resources on unneeded data.
