SagaCsv
CSV encoding and decoding
Guide
Getting started
Install saga_csv, build the NIF, and parse your first row. Also: how this project is laid out as a rebar3 + rustler example.
Reading CSV
parse vs parse_keyed, configuring the reader, skipping headers, and how quoting/CRLF are handled.
Writing CSV
write vs write_keyed, attaching headers, custom separators, and what gets quoted automatically.
