Struct csv::Encoded

pub struct Encoded { /* fields omitted */ }

A record to be encoded.

This is a "wrapper" type that allows the Encoder machinery from the serialize crate to encode a single CSV record from your custom types.

Generally, you should not need to use this type directly. Instead, you should prefer the encode or encode_all methods defined on CsvWriter.

Methods

impl Encoded

fn new() -> Encoded

Creates a new encodable record. The value returned can be passed to Encodable::encode.

fn unwrap(self) -> Vec<ByteString>

Once a record has been encoded into this value, unwrap can be used to access the raw CSV record.
