Crate cinrs_macros 

The procedural macro front end for cinrs.

Deliberately a thin shim: everything interesting lives in cinrs-core, which is built on proc-macro2 and can therefore be tested without a procedural macro context.

The nightly feature

cinrs-core never touches proc_macro, so the one thing it cannot do by itself is build a span that points inside a string literal — proc_macro::Literal::subspan is unstable on every channel, and proc-macro2 does not expose it. With the nightly feature this crate turns on #![feature(proc_macro_span)] and hands the front end a Subspan hook that does exactly that, so a c99! { r#"…"# } body reports its errors on the offending C token rather than on the whole literal with the position spelled out in the message. Everything else is unchanged, and without the feature — or wherever subspan declines to answer, as under rust-analyzer — the stable behaviour comes back on its own.
