It took a little work reading the syn documentation, but once we got the hang of it, we can now work with real Rust source code and turn it into something we can use. Oh, before we go, let's clean one thing up.

- taiki-e/syn-serde Apologies in advance for how silly this probably is. I have some familiarity with the visitor pattern and AST parsing, but almost none with Rust. Using some examples and comments from other issues, I was able to get a broken rough protot Source to the Rust file `runtime-attributes/src/lib.rs`.

Trait implementations are provided for primitives, some std types, and some syn types. FromDeriveInput is implemented or derived by each proc-macro crate which depends on darling . This is the root for input parsing; it gets access to the identity, generics, and visibility of the target type, and can specify which attribute names should be parsed or forwarded from the input AST. Syn is a parsing library for parsing a stream of Rust tokens into a syntax tree of Rust source code. Currently this library is geared toward use in Rust procedural macros, but contains some APIs that may be useful more generally.
