antigen-macros

Procedural macros for the antigen crate.

This crate is the proc-macro implementation backing antigen. Most users should depend on antigen directly, which re-exports these macros. Direct use of antigen-macros is supported but not the primary path.

Macros provided (all re-exported from antigen):

• #[antigen(...)] — declare a named failure-class with a structural fingerprint
• #[presents(...)] — mark code as exhibiting a failure-class pattern
• #[immune(...)] — declare immunity with a witness reference
• #[descended_from(...)] — propagate failure-class markers through structural derivation
• #[antigen_tolerance(...)] — mark deliberate exceptions with rationale

See the antigen crate for usage documentation and github.com/antigen-rs/antigen for the full project substrate.
