1//! The Vector Core Library
2//!
3//! The Vector Core Library are the foundational pieces needed to make a vector
4//! and is not vector with pieces missing. While this library is obviously
5//! tailored to the needs of vector it is written in such a way to make
6//! experimentation and testing _in the library_ cheap and demonstrative.
7//!
8//! This library was extracted from the top-level project package, discussed in
9//! RFC 7027.
