minivariant 1.0.0

Minivariant: Simple, focused variant library

Goal

Minivariant provides a simple way to work with a tagged union. It aims to provide a replacement for std.variant.Algebraic, which is built on top of std.variant.Variant.

The issue that spawned this effort was the inability of Algebraic to work with basic type conversion, e.g. it triggers a static assertion failure to assign an immutable int to an Algebraic containing an int.

Overview

The main type is minivariant.variant.Variant. It takes a tuple of accepted parameters:

auto my_variant = Variant!(uint, char, bool, string)("Hello world");

It provides a pedestrian usage, via isType and peek, and a more structured approach via visit.
