Generic library for vectors with statically known size. Implementation is based on http://unlines.wordpress.com/2010/11/15/genericsforsmallfixedsizevectors/ Same functions could be used to work with both ADT based vector like
data Vec3 a = a a a
Tuples are vectors too:
sum (1,2,3)
6
Vectors which are represented internally by arrays are provided by library. Both boxed and unboxed arrays are supported.
Library is structured as follows:
Data.Vector.Fixed Generic API. It's suitable for both ADTbased vector like Complex and arraybased ones.
Data.Vector.Fixed.Cont Continuation based vectors. Internally all functions use them.
Data.Vector.Fixed.Mutable Type classes for arraybased implementation and API for working with mutable state.
Data.Vector.Fixed.Unboxed Unboxed vectors.
Data.Vector.Fixed.Boxed Boxed vector which can hold elements of any type.
Data.Vector.Fixed.Storable Unboxed vectors of Storable types.
Data.Vector.Fixed.Primitive Unboxed vectors based on pritimive package.
Changes
Changes in 1.2.0.0
Show
instance for data type now respect precedence.
Changes in 1.1.0.0
 GHC8.4 compatibility release. Semigroup instances added and semigroup dependency added for GHC7.10
Changes in 1.0.0.0

Vector length now expressed as GHC’s type level literals. Underlying implementation still uses Peano numbers to perform induction. This doesn’t change user facing API much. Notably
FlexibleInstances
andGADTs
/TypeFamiles
are now required to writeArity
constraint. 
Monad
constraint is relaxed toApplicative
where applicable. Duplicate functions are removed (sequence
&sequenceA
→sequence
, etc) 
Module
Data.Vector.Fixed.Monomorphic
is dropped. 
Construction of Nary vectors reworked.
Make
type class is gone. 
Boxed arrays now use SmallArrays internally.

overlaps
is removed from API for mutable vectors. 
Data.Vector.Fixed.defaultRnf
is added. 
Data.Vector.Fixed.Mutable.lengthI
is dropped.
Changes in 0.9.0.0

Changes in 0.5.0.0

ContVec
now behaves like normal vector.Arity
type class is reworked. `Id’ data type is removed. 
Construction of vector reworked.
