Struct Factory 

pub struct Factory<T: Middleware> { /* private fields */ }

Implementations

impl<T: Middleware> Factory<T>

pub fn new(client: Arc<T>) -> Self

pub async fn deploy_from_file( &self, path: &Path, init: Init, overridden_params: Option<TransactionParams>, do_contract_compression: bool, ) -> Result<BaseContract<T>, Error>

The deploy_from_file function deploys a contract from a file path, with the option to override transaction parameters.

Arguments:

• path: The path parameter is a reference to a Path object, which represents the path to a file. It is used to specify the location of the file from which the contract code will be read.
• init: The init parameter is of type Init. It represents the initialization parameters for the contract being deployed. The specific structure and fields of the Init type would depend on the contract being deployed.
• overridden_params: overridden_params is an optional parameter of type TransactionParams. It allows you to override the default transaction parameters when deploying the contract. If you don’t want to override any parameters, you can pass None as the value for this parameter.
• do_contract_compression: Set it to true if you want your contract gets compressed before deployment.

Returns:

a Result object with a value of type BaseContract<T> if the operation is successful, or an Error object if there is an error.

use zilliqa_rs::providers::{Http, Provider};
use zilliqa_rs::contract::ScillaVariable;
use zilliqa_rs::signers::LocalWallet;
use zilliqa_rs::contract::Init;
use zilliqa_rs::contract::ContractFactory;
use std::path::PathBuf;

    let provider = Provider::<Http>::try_from(END_POINT)?
        .with_chain_id(222)
        .with_signer(wallet.clone());

    let factory = ContractFactory::new(provider.into());
    let init = Init(vec![ScillaVariable::new_from_str("_scilla_version", "Uint32", "0")]);
    let contract = factory.deploy_from_file(&PathBuf::from("./tests/contracts/Timestamp.scilla"), init, None, false).await?;
    println!("addr: {:?}", contract);
    Ok(())
}

pub async fn deploy_str( &self, contract_code: String, init: Init, overridden_params: Option<TransactionParams>, ) -> Result<BaseContract<T>, Error>

The deploy_str function deploys a contract with the given code and initialization parameters, and returns a BaseContract object.

Arguments:

• contract_code: A string containing the code of the contract to be deployed.
• init: The init parameter is of type Init, which is a custom struct or enum that contains the initialization data for the contract.
• overridden_params: overridden_params is an optional parameter of type Option<TransactionParams>. It allows the caller to provide custom transaction parameters for deploying the contract.

Returns:

The function deploy_str returns a Result containing either a BaseContract<T> or an Error.
