+//! Macros to derive runtime debug implementation.
+//!
+//! This custom derive implements a `core::fmt::Debug` trait,
+//! but in case the `std` feature is enabled the implementation
+//! will actually print out the structure as regular `derive(Debug)`
+//! would do. If `std` is disabled the implementation will be empty.
+//!
+//! This behaviour is useful to prevent bloating the runtime WASM
+//! blob from unneeded code.
+//!
+//! ```rust
+//! #[derive(sp_debug_derive::RuntimeDebug)]
+//!	struct MyStruct;
+//!
+//!	assert_eq!(format!("{:?}", MyStruct), "MyStruct");
+//! ```
+
+extern crate proc_macro;
+
+mod impls;

+#[proc_macro_derive(RuntimeDebug)]

+   impls::debug_derive(syn::parse_macro_input!(input))
