Fibers are an abstraction over sequential computation, similar to threads but at a higher level. There are two ways to think about this model: by example, and abstractly from first principles. We'll start with the example.
(credit here is very much due to Fabio Labella, who's incredible Scala World talk describes these ideas far better than I can)
Consider the following three functions
| case object DateCoercionViolation extends ValueCoercionViolation("Date value expected") | |
| def parseDate(s: String) = Try(new DateTime(s, DateTimeZone.UTC)) match { | |
| case Success(date) => Right(date) | |
| case Failure(_) => Left(DateCoercionViolation) | |
| } | |
| val DateTimeType = ScalarType[DateTime]("DateTime", | |
| coerceOutput = date => ast.StringValue(ISODateTimeFormat.dateTime().print(date)), | |
| coerceUserInput = { |
