Has the Rust Grammar Working Group abandoned the canonization of the Rust grammar?

This page summarizes the projects mentioned and recommended in the original post on /r/rust

Our great sponsors
  • WorkOS - The modern identity platform for B2B SaaS
  • InfluxDB - Power Real-Time Data Analytics at Scale
  • SaaSHub - Software Alternatives and Reviews
  • wg-grammar

    Where the work of WG-grammar, aiming to provide a canonical grammar for Rust, resides

  • The repo https://github.com/rust-lang/wg-grammar has not been updated since 2019, so I'm wondering if the project is still active

  • reference

    The Rust Reference (by rust-lang)

  • There is no normative document. However, the Rust Reference is a best-effort attempt to describe Rust, and any feature's page will contain the syntax rules for that feature (e.g. https://doc.rust-lang.org/reference/comments.html ), and if the grammar on any such page is wrong it would be considered a bug and corrections can be submitted to https://github.com/rust-lang/reference .

  • WorkOS

    The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  • mrustc

    Alternative rust compiler (re-implementation)

  • The "bnf" folder in the mrustc has a more practical attempt at a working grammar: https://github.com/thepowersgang/mrustc/tree/master/bnf
