In Python I use builtin ast; in Java I use javaparser; in C I wrote a custom parser/emitter; in TypeScript I use builtin functions; …

What should I use in Rust? - In the past I've hacked away with nom, syn, quote, and prettyplease… it would be nice to see a higher level API that enables:

• parsing—without evaluation—and emission of the following:
  • derives and other macros
  • imports (use)
  • structs
  • impl blocks
  • fn prototypes (I don't care about body-parsing, just want to understand the interface and be able to replace the interface and push the body back verbatim)
  • global const / let bindings
  • comments

Thanks
