TypeDescriptorProviderImpl

object TypeDescriptorProviderImpl

This class contains the core macro implementations. This is in a separate module to allow it to be in a separate compilation unit, which makes it easier to provide helper methods interfacing with macros.

  13. def evidentColumn(c: Context, allowUnknown: Boolean = false)(tpe: scala.reflect.macros.Universe.Type): Option[Int]

    When flattening a nested structure with Options, the evidentColumn is a column, relative to the the first 0-offset column, that represents evidence of this T, and hence set of columns, are present or absent.

    When flattening a nested structure with Options, the evidentColumn is a column, relative to the the first 0-offset column, that represents evidence of this T, and hence set of columns, are present or absent. This is to handle Option types in text files such as CSV and TSV. a type T is evident if it the evidentColumn.exists

    primitive numbers are evident case classes are evident if they have at least one evident member.

    Strings are not evident (we can't distinguish Empty from "") Option[T] is not evident (we can't tell Some(None) from None).
