Returns two distinct pseudo-random number generators. Implementations should take care to ensure that the resulting generators are not correlated.
Splits a pseudo-random number generator into two. Overwrites the mutable pseudo-random number generator with one of the immutable pseudo-random number generators produced by a split function and returns the other.
Splits a pseudo-random number generator into two. Overwrites the mutable wrapper with one of the resulting generators and returns the other as a new mutable generator.
Pseudo-random generators that can be split into two separate and independent psuedo-random generators should provide an instance for this type class. Historically this functionality was included in the RandomGen type class in the split function, however, few pseudo-random generators possess this property of splittability. This lead the old split function being usually implemented in terms of error.
