Struct csv::Decoded
[−]
[src]
pub struct Decoded { /* fields omitted */ }A record to be decoded.
This is a "wrapper" type that allows the Decoder machinery from the
serialize crate to decode a single CSV record into your custom types.
Generally, you should not need to use this type directly. Instead, you
should prefer the decode or decode_all methods defined on CsvReader.
Methods
impl Decoded[src]
fn new(bytes: Vec<ByteString>) -> Decoded
Creates a new decodable record from a record of byte strings.
