OSV is a high-performance CSV parser for Ruby, implemented in Rust. It wraps BurntSushi's csv-rs crate to provide fast CSV parsing with support for both hash-based and array-based row formats. Features include: Flexible input sources (file paths, gzipped files, IO objects, strings), configurable parsing options (headers, separators, quote chars), support for both hash and array output formats, whitespace trimming options, strict or flexible parsing modes, and is significantly faster than Ruby's standard CSV library.
