Module documentation for 1.0.0.0

Used by 2 packages in nightly-2018-04-04(full list with versions):

Vector Sized

This package exports a newtype tagging the vectors from the vector package with a type level natural representing their size. It also exports a few functions from vector appropriately retyped.

This package is fairly similar to the fixed-vector package. While both provide vectors of statically know length they use completely different implementation with different tradeoffs. vector-sized is a newtype wrapper over vector thus it’s able to handle vectors of arbitrary length but have to carry runtime representation of length which is significant memory overhead for small vectors. fixed-vector defines all functions as manipulations of Church-encoded product types (∀r. (a→a→r) → r for 2D vectors) so it can work for both arbitrary product types like data V2 a = V2 a a and opaque length-parametrized vectors provided by library. As consequence of implementation it can’t handle vectors larger than tens of elements.

The initial code for this package was written by @bgamari in a PR for vulkan
