Documentation
class (Integral (Index seq), GrowingAppend seq) => SemiSequence seq where Source #
SemiSequence was created to share code between IsSequence and NonNull.
Semi means SemiGroup
A SemiSequence can accomodate a SemiGroup such as NonEmpty or NonNull
A Monoid should be able to fill out IsSequence.
SemiSequence operations maintain the same type because they all maintain the same number of elements or increase them.
However, a decreasing function such as filter may change they type.
For example, from NonEmpty to '[]'
This type-changing function exists on NonNull as nfilter
filter and other such functions are placed in IsSequence
NOTE: Like GrowingAppend, ideally we'd have a Semigroup superclass
constraint here, but that would pull in more dependencies to this package
than desired.
