Data.Sequences

Description

Abstractions over sequential data structures, like lists and vectors.

Synopsis

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.
