Trait Implementations§

Source §

impl<R> RowDecoder for JsonlDecoder<R>
where R: BufRead,

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

Source §

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

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