reify_types - Use the definition of your types after its definition

This crate provides a machinery to allow your types "reified" later; i.e. any external crate can use the definition of the type!

This consists of two major parts:

• Reify trait - provides T::reify() static method that returns the definition of type T as DeriveInput.
  • It also comes with ReifyStruct and ReifyEnum that is specialized to structs and enums.
• Reify derive macro - automatically derives Reify and related specialized types.

With this crate, you can mimic the reification mechanism in TemplateHaskell. Current limitations:

• Only types with Reify impl can be reified.
• It uses ToTokens and parse_quote! under the hood, so the performance can be poor for large types.
