metastruct

Metastruct is Rust library for metaprogramming with struct fields.

Some of the things you can do with metastruct include:

• Iterate over a struct's fields.
• Map a closure over all or some of a struct's fields.
• Access the number of fields in a struct at compile-time via a const.

This is achieved by a procedural macro, which generates macro_rules! macros.

One way of understanding metastruct is as a shortcut to writing your own derive macros. If you have a trait that you'd like to implement on a one-off basis, metastruct can help you write that implementation without a derive macro.

:construction: Under Construction :construction:

This library is currently under construction and should not be considered stable.

There's currently no documentation aside from a few scant code comments and examples/tests.
