AIP-91 is now approved by the Aptos governance process.

Enum types in Move allow developers to define structured data with multiple variants.

Better code readability and maintainability
Complex data transformations made easier
With versioning, enum types allow data to evolve over time without breaking compatibility.

Simply put: Enum types facilitate upgradable, efficient data structures for longer-term smart contract management, without any changes to underlying storage or serialization. Learn more:

# AIP-91 - Enum Types in the Move VM

## Summary

Move-2 adds a collection of new features to the Move language as it is used on Aptos. Enum types (often also referred to as *algebraic data types*, ADT) is one of those features. Move enum types allow to specify a set of _variants_ of the structure of a value. Code can be written which inspects values at runtime, matching over the possible variants. In this AIP the extensions to the Move VM enabling enum types are described.

If I’m doing a delegate, am I eligible to vote? Or is it only my validator who I delegated my APTs to?
