Once you've deployed your contract, as seen in the previous sections, you'll likely want to:
Here's an example. Suppose your Sway contract has two ABI methods called initialize_counter(u64)
and increment_counter(u64)
. Once you've deployed it the contract, you can call these methods like this:
// This will generate your contract's methods onto `MyContract`.
// This means an instance of `MyContract` will have access to all
// your contract's methods that are running on-chain!
abigen!(Contract(
name = "MyContract",
abi = "e2e/sway/contracts/contract_test/out/release/contract_test-abi.json"
));
// This is an instance of your contract which you can use to make calls to your functions
let contract_instance = MyContract::new(contract_id_2, wallet);
let response = contract_instance
.methods()
.initialize_counter(42) // Build the ABI call
.call() // Perform the network call
.await?;
assert_eq!(42, response.value);
let response = contract_instance
.methods()
.increment_counter(10)
.call()
.await?;
assert_eq!(52, response.value);
The example above uses all the default configurations and performs a simple contract call.
Furthermore, if you need to separate submission from value retrieval for any reason, you can do so as follows:
let response = contract_instance
.methods()
.initialize_counter(42)
.submit()
.await?;
let value = response.response().await?.value;
Next, we'll see how we can further configure the many different parameters in a contract call.
