Implementations

impl<M: Middleware> ERC20PresetMinterPauser<M>

pub fn new<T: Into<Address>>(address: T, client: Arc<M>) -> Self

Creates a new contract instance with the specified ethers client at address. The contract derefs to a ethers::Contract object.

pub fn deploy<T: Tokenize>( client: Arc<M>, constructor_args: T, ) -> Result<ContractDeployer<M, Self>, ContractError<M>>

Constructs the general purpose Deployer instance based on the provided constructor arguments and sends it. Returns a new instance of a deployer that returns an instance of this contract after sending the transaction

Notes:

• If there are no constructor arguments, you should pass () as the argument.
• The default poll duration is 7 seconds.
• The default number of confirmations is 1 block.

Example

Generate contract bindings with abigen! and deploy a new contract instance.

Note: this requires a bytecode and abi object in the greeter.json artifact.

    abigen!(Greeter, "../greeter.json");

   let greeter_contract = Greeter::deploy(client, "Hello world!".to_string()).unwrap().send().await.unwrap();
   let msg = greeter_contract.greet().call().await.unwrap();
