- derive-deftly is a Rust package for defining derive macros without writing low-level procedural macros.
- It offers an easy-to-learn syntax but is powerful enough for complex macros.
- Provides comprehensive reference documentation including a template language reference manual and rustdoc.
- Example shown for deriving field accessor functions to avoid manual, error-prone implementations.
- Supports defining templates for structs, enums, and unions, but not functions or impl blocks.
- Templates can define new types, functions, methods, and variables, and inspect input types.
- Limitations include not being able to modify the original type and requiring specific syntax for application.
