Namespace for unsigned‐integer packing types and BDEX helpers.

== Synopsis

Declared in `<bdlc_packedintarray.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
struct PackedIntArrayImp_Unsigned;
----

== Description

This `struct` provides a namespace for types and methods used to implement a space‐efficient value‐semantic array class representing a sequence of `TYPE` elements; `TYPE` must be convertible to either a `bsl::uint64_t`. Specifically, it defines the types used to store the array's data, methods needed to externalize and unexternalize the array, and a method to determine the storage size to use for a given value.
