Struct SmartContractInputs 

pub struct SmartContractInputs {
    pub version: i32,
    pub account_info: AccountInfo,
    pub protocol_input: ProtocolInputs,
    pub contract_input: ContractInputs,
}

SmartContractInputs represents the entire bundle of inputs sent into a Versatus smart contract. It is a collection of input data from a variety of locations, including the contract caller, and the protocol accounts database.

Fields

version: i32

Version of the compute stack and API/ABI

account_info: AccountInfo

Account info as provided by the protocol

protocol_input: ProtocolInputs

Protocol inputs as provided by the protocol

contract_input: ContractInputs

Application inputs as provided by the application via the protocol

Implementations

impl SmartContractInputs

pub fn gather() -> Result<Self>

Read JSON data on stdin and deserialise it to a set of Rust data structures.

pub fn account_info(&self) -> AccountInfo

Returns a copy of the associated account information

pub fn account_addr(&self) -> Address

Returns the address of the associated account
