Utilities for BER integer encoding and decoding.

== Synopsis

Declared in `<balber_berutil.h>`

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

== Description

This component‐private utility `struct` provides a namespace for a suite of functions used by `BerUtil` to implement BER encoding and decoding operations for integer values. Within the definition of this `struct`:
