This is a tiny type-checker for data in Nix, written in Nix.
Features:
- Checking of primitive types (
int,stringetc.) - Checking polymorphic types (
option,list,either) - Defining & checking struct/record types
- Defining & matching enum types
- Defining & matching sum types
- Defining function signatures (including curried functions)
- Types are composable!
option string!list (either int (option float))! - Type errors also compose!
Lacking:
- Any kind of inference
- Convenient syntax for attribute-set function signatures
