This is a workshop/repository by the Rust developer David Tolnay (dtolnay) intended to teach how to write Rust procedural macros (derive macros, function-like macros, attribute macros). The repo contains multiple toy/realistic macro projects drawn from real use-cases: e.g., derive(Builder), derive(CustomDebug), seq!, #[sorted], #[bitfield]. The README indicates the focus is on learning: parsing token streams, generating code, handling generics, attribute arguments, etc. It has test harness and workflow guidance. ...

This is a Rust crate that provides a convenient derive macro (#[derive(Error)]) for implementing std::error::Error on your custom error types (structs or enums). The goal is to enable library authors to build expressive, typed error types, with readable Display implementations (via #[error("...")] annotations) as well as From conversions (#[from]), source tracking (#[source]), and optionally backtraces. It is designed so that switching from handwritten error implementation to using this...

...Decoding and encoding rust values into Erlang terms is as easy as a function call. Making a Rust struct encodable and decodable to Erlang or Elixir can be done with a single attribute. Enables you to safely pass a reference to a Rust struct into Erlang code. The struct will be automatically dropped when it's no longer referenced.

...Let's define a simple Sum message with two usize parameters and an actor which will accept this message and return the sum of those two numbers. Here we use the #[actix::main] attribute as an easier way to start our System and drive our main function.

BGP route explorer for RIB (routing information database) with ability to drill-down routes change history. It can be a BGP speaker (only listener exact) or BMP monitoring station. bgpexplorer supports many NLRI types and path attribute kinds and intened to be a looking glass and "show route" replacement. It is replacement for old BGPHist (https://sourceforge.net/projects/bgphist/). bgpexplorer is much more fast, beacause it store RIBs with history in the RAM. RIB can be accessed via http protocol in JSON format. For your convinience bgpexplorer serves bundled files to provide basic web service, which can be used as backend for front web server (nginx or apache for example) with AAA.
