- 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`.

use syn::{Error, Ident, LitStr, Result, Token}; use syn:: parse:: ParseStream; // Parses input that looks like `name = "string"` where the key must be // the identifier `name` and the value may be any string literal. syn, a parser for Rust token streams. quote provides a handy way to produce Rust token streams by writting Rust code. Using these libraries, we can write a simple procedural macro attribute that’d be a drop-in replacement for the standard # [test] attribute. Perhaps my favorite feature in the Rust 2018 edition is procedural macros.Procedural macros have had a long and storied history in Rust (and will continue to have a storied future!), and now is perhaps one of the best times to get involved with them because the 2018 edition has so dramatically improved the experience both defining and using them.
