closed-trait-macros

The attribute macros behind closed-trait. This crate is an implementation detail: it exports #[sealed] and #[enumerate] but not the traits their expansions refer to, so on its own it does not compile into anything useful.

Depend on the facade instead, which re-exports both attributes:

[dependencies]
closed-trait = "<latest-version>"

Everything (what the macros do, their options, and the traits they generate impls for) is documented there: https://docs.rs/closed-trait.
