//! 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");
|
|
//! ```
