CsvIterator

io.github.quafadas.scautable.CsvIterator
class CsvIterator[K <: Tuple](filePath: String) extends Iterator[NamedTuple[K, StringyTuple[K & Tuple]]]

A NamedTuple representation of a CSV file.

It is a (lazy) iterator that reads a CSV file line by line and converts each line into a NamedTuple.

Attempting to use the iterator a second time will throw a StreamClosedException. Common usage

def csvIterator = CSV.resource("simple.csv")
val csvData = csvIterator.toSeq

Note that at this point, you are plugged right into the scala collections API.

csvData.filter(_.column("colA") == "foo").drop(10).take(5).map(_.column("colB"))

etc
