Non-empty Vectors

Build Status Hackage

This package provides thin wrappers around mutable and immutable vector types that enforce non-emptiness, with APIs for both boxed and unboxed storage.

Storage Immutable Mutable
Boxed Data.Vector.NonEmpty Data.Vector.NonEmpty.Mutable
Unboxed Data.Vector.NonEmpty.Unboxed Data.Vector.NonEmpty.Unboxed.Mutable

The unboxed API requires Unbox instances for element types. Operations that can produce an empty result return an ordinary vector or Maybe, as appropriate. The Internal modules expose constructors for users who manage the non-emptiness invariant themselves.

Library dependencies are base, deepseq, primitive, and vector.
