//! Some instance placeholder to be used in [`frame_support::pallet`] attribute macro.
//!
//! [`frame_support::pallet`] attribute macro does only requires the instance generic `I` to be
//! static (contrary to `decl_*` macro which requires instance generic to implement
//! [`frame_support::traits::Instance`]).
//!
//! Thus support provides some instance types to be used, This allow some instantiable pallet to
//! depend on specific instance of another:
//! ```
//! # mod another_pallet { pub trait Config<I: 'static = ()> {} }
//! pub trait Config<I: 'static = ()>: another_pallet::Config<I> {}
//! ```
//!
//! NOTE: [`frame_support::pallet`] will reexport them inside the module, in order to make them
//! accessible to [`frame_support::construct_runtime`].
