Trait Implementations

impl<R: BufRead> RowDecoder for CsvDecoder<R>

fn header(&mut self) -> Result<Option<Vec<String>>>

Returns the column names declared in the file header. CSV uses this; JSONL/JSON return None (every row carries its own keys).

fn next_row(&mut self) -> Result<Option<Vec<(String, LoraValue)>>>

Pull the next row as a flat (name, value) vector. Returns Ok(None) once the input is exhausted.
