Handy way of casting to a contract proxy trait.
Would make more sense to be in dharitri-wasm-derive, but Rust “cannot export macro_rules! macros from a proc-macro
crate type currently”.
Imports required for deriving serialization and TypeAbi.
Getting all imports needed for a smart contract.
Compact way to represent the BorrowedMutStorage type.
Converts usize to NonZeroUsize or returns SCError.
Very compact way of not allowing anyone but the owner to call a function.
Allows us to write Solidity style require!(<condition>, <error_msg>)
and avoid if statements.
Compact way of returning a static error message.
Equivalent of the ? operator for SCResult.
