Enums with data in Solidity

Use cases

  • Optional/nullable data types.
  • Variant data types.
  • Flag with extra information needed only in some cases (or different in different cases).
  • Modeling states in a state machine where each state can have some data associated with it.
  • List of operations for batch processing, where each operation can have its own arguments.
  • Alternative to function overloading that allows avoiding combinatorial explosion when there are multiple parameters that need variants.
  • Nested data structures with heterogenous nodes.
