Provides ways to create instances of Builder for arbitrary collection types.
Provides ways to create instances of Builder for arbitrary collection types.
This is a bit like CanBuildFrom (and instances of HasBuilder can be derived automatically for any type that
has a CanBuildFrom), but simpler (no From type parameter, no variance, ...) and with one critical difference:
all the default instances are Serializable, meaning that type classes that depend on HasBuilder can be
used with Apache Spark and other framework that, unfortunately, rely on serialisation.
