SumType is a generic sum type for modern D. It is meant as an
alternative to `std.variant.Algebraic`.
Features:
- Pattern matching, including support for structural matching
(*)
- Self-referential types, using `This`
- Works with `pure`, `@safe`, `@nogc`, and `immutable` (*)
- Zero runtime overhead compared to hand-written C
- No heap allocation
- Does not rely on runtime type information (`TypeInfo`) (*)
Starred features (*) are those that are missing from `Algebraic`.
Code examples are available in the documentation (linked below).
New in this release:
- The list of types allowed in a sum type is now public
- Implicit qualifier conversions are now allowed in pattern
matching
- Better code examples in the documentation
This library is a work in progress. If you have a use case you'd
like to see supported, or an API you'd like to see implemented,
please get in touch!
