Struct CsvRenderer 

pub struct CsvRenderer<O: TextOut> { /* private fields */ }

Renders TableRows/1 as CSV.

One schema first, rows exactly as wide as the schema, one end: anything else is PROTOCOL_ORDER_ERROR. A schema with no columns has no CSV form (a record cannot be empty) and is TARGET_VALUE_UNREPRESENTABLE. Every record, the header included, ends with the configured newline, the last one too. The output is flushed once, at End, so a table that fails half way is not flushed as if it were whole; a failure found after any text was written says so with committed_output.
