Struct pallet_contracts::Environment

pub struct Environment<T: Config> { /* private fields */ }

List of all runtime configurable types that are used in the communication between pallet-contracts and any given contract.

Since those types are configurable they can vary between chains all using pallet-contracts. Hence we need a mechanism to communicate those types in a way that can be consumed by offchain tooling.

This type only exists in order to appear in the metadata where it can be read by offchain tooling.
