Lib.rs

A crate that provides means of executing/dispatching calls into the runtime.

There are a few responsibilities of this crate at the moment:

• It provides an implementation of a common entrypoint for calling into the runtime, both wasm and compiled.
• It defines the environment for the wasm execution, namely the host functions that are to be provided into the wasm runtime module.
• It also provides the required infrastructure for executing the current wasm runtime (specified by the current value of :code in the provided externalities), i.e. interfacing with wasm engine used, instance cache.
