CsvEncoder

Struct CsvEncoder 

Source
pub struct CsvEncoder { /* private fields */ }
Available on crate feature csv only.
Expand description

Per-stream state for CsvStreamFormat.

A fresh csv::Writer is built for every row, because csv writes its header from the first serialised record and there is no way to ask an existing writer to stop. The header therefore has to be produced by a writer configured for it, and every later row by one that is not.
