Constant CLOUDFLARE_ADAPTER_SRC 

pub const CLOUDFLARE_ADAPTER_SRC: &'static str;

The first-party Cloudflare platform adapter (v0.19): the platform’s real infrastructure capabilities, as they are — no portable intersection (decision 0016). The v0.19 surface was the minimal, collection-free Kv (decision 0023); v0.23 adds the list drain and putTtl (0050/0051); structured values are v0.22-codec composition, and Queue remains its own future increment. Like the bynk surface it has no binding clause — the toolchain supplies the binding.
