Trait Implementations

impl<W> RowEncoder for JsonArrayEncoder<W>

where W: Write,

fn begin(&mut self, _columns: &[String]) -> Result<(), Error>

Emit any header bytes the format needs (CSV header row, opening [ for the JSON array). Must be called exactly once before any write_row.

fn write_row(&mut self, row: &Row) -> Result<(), Error>

Write one row. The encoder pulls column names from the row’s Row::iter_named iterator — they must align with the columns passed to Self::begin, in the same order, for CSV.

fn write_named_row( &mut self, columns: &[(String, LoraValue)], ) -> Result<(), Error>

Write the same shape as Self::write_row from a flat (name, value) slice. Used by encoders that consume rows from outside the engine (testing, replay).

fn finish(&mut self) -> Result<(), Error>

Emit any trailer (closing ] for the JSON array) and flush the writer.
