[Haskell-cafe] ANN: fixed-vector

[Aleksey Khudyakov]

Hello cafe!

I want to announce library for the small vectors of fixed length
fixed-vector[1]. Fixed means that vector's length is determined
by its type.

Generic API can work with both ATD-based vector like complex or
Vec written below and array-based ones.

> data Vec a = Vec a a a

It's based on post by Roman Leschinsiy[2].


Library also provide array-based vectors with memory
representation similar to onves from vector package. It's more
compact though because there is no need to store lengh and and
offset to first element.
