Function casper_contract::contract_api::runtime::call_versioned_contract

pub fn call_versioned_contract<T: CLTyped + FromBytes>(
    contract_package_hash: ContractPackageHash, 
    contract_version: Option<ContractVersion>, 
    entry_point_name: &str, 
    runtime_args: RuntimeArgs
) -> T

Invokes the specified entry_point_name of stored logic at a specific contract_package_hash address, for the most current version of a contract package by default or a specific contract_version if one is provided, and passing the provided runtime_args to it

If the stored contract calls ret, then that value is returned from call_versioned_contract. If the stored contract calls revert, then execution stops and call_versioned_contract doesn’t return. Otherwise call_versioned_contract returns ().
