Nope. Rust reference says that in very red rectangle: Warning: This book is incomplete. Documenting everything takes a while. See the GitHub issues for what is not documented in this book.

Ferrocene have specification. That one is good enough to present to various bureaucrats, but it's very imprecise.

> you just say "this code needs edition 2018", and there's your spec.

Rust doesn't work like that. I can use “Rust edition 2015” and yet still use facilities that weren't available in year 2023, easily.

Rust edition is for breaking changes, not for supporting frozen-in-time toolchains.

Rust community stance for the demand to provide support for ancient compilers in the various crates was always: “you invent artificial limitations, you support artificial limitations… could fork old versions of old crates or do whatever you want, that's not our problem”.
