契约

• CSV::FieldInfo provides 0-based column index, 1-based logical line number, and transformed header symbol metadata to custom converters registered in CSV::Converters.
• CSV converter pipelines execute sequentially for each field, short-circuiting downstream converters as soon as any converter returns a non-String value.
• CSV.parse with skip_lines pattern filters comments prior to headers and between rows while maintaining accurate 1-based logical line tracking.
• CSV.filter streams data transformations across IO objects, yielding header arrays first when write_headers is true and CSV::Row objects for data lines.
• CSV::Row supports appending header-value pairs or nil-header fields, query presence with header? and field?, and column deletion returning key-value pairs.
