The build fails because the crate uses nightly-only feature gates (mutex_unlock, async_closure in tinydancer/src/main.rs) that current nightly has removed, and nothing pins a compatible toolchain — the locked proc-macro2 1.0.51 also fails to compile on a modern nightly (unknown feature proc_macro_span_shrink).

Fixed in #41 by pinning nightly-2022-11-02 (the same nightly the diet-rpc-validator fork uses) via rust-toolchain.toml and repairing the CI workflow (system deps, modern actions). A green full build is linked in the PR.
