factories

Standardized Scala factory methods with accumulated error messages.

Overview

The primary use case of factories is implementing your typical factory/ apply method of a value class. However, the library does not make assumptions about what a factory method creates, so it should be applicable to other contexts as well.

The creation of factories methods is supported by way of

• a standardized (constraint) syntax and
• typeclass-based implementations of said constraints for various types.

In this regard, typical examples for constraints are numeric range restrictions or strings matching a regular expression.
