maximelenoir / partial-enum Goto Github PK

Nice crate - I'm keen to try it in a few contexts.

However, the docs say:

By default, the empty placeholder is the unit type (). The generated code is compatible with the stable compiler.

Unfortunately, even with the "never" feature disabled, the use of #![feature(...)] is not available with a stable release channel of rustc (e.g. 1.77.2):

error[E0554]: `#![feature]` may not be used on the stable release channel
 --> .../.cargo/registry/src/index.crates.io-6f17d22bba15001f/partial-enum-0.0.4/src/lib.rs:1:1
  |
1 | #![feature(never_type)]
  | ^^^^^^^^^^^^^^^^^^^^^^^

Is there an easy way to get this working with a stable rustc?
