Substrate runtime api
The Substrate runtime api is the crucial interface between the node and the runtime.
Every call that goes into the runtime is done with a runtime api. The runtime apis are not fixed.
Every Substrate user can define its own apis with
decl_runtime_apis and implement them in
the runtime with impl_runtime_apis.
Every Substrate runtime needs to implement the [Core] runtime api. This api provides the basic
functionality that every runtime needs to export.
Besides the macros and the [Core] runtime api, this crates provides the [Metadata] runtime
api, the [ApiExt] trait, the [CallApiAt] trait and the [ConstructRuntimeApi] trait.
On a meta level this implies, the client calls the generated API from the client perspective.
