Detailed Description

Fixed-size portable codecs for paged persistent tree payloads.

This header centralizes the little-endian fixed-size serialization used by Aleph's paged persistent B-Tree and B+ Tree implementations. The default codecs cover integral types, enums, IEEE-754 float/double, and std::array compositions thereof.
