Detailed Description

Purpose

Provide a variant type ('Datum') and supporting utilities.

Mnemonic

Basic Development Library Datum (bdld)

Description

The 'bdld' package defines in bdld_datum a type that can contain an assortment of different value types, including user-defined types. Other components provide utilities for assembling arrays and maps of 'Datum' objects.

Note that 'bdld::Datum' has many features of value-semantic types (including an 'operator=='), but is not a VST. See {bdld_datum } component documentation.
