},
});

Serverless Functions.

Enhance Juno's capabilities with strongly-typed hooks, automatically triggered to execute custom logic on your smart contract.

#[derive(Serialize, Deserialize)]
struct Person {
hello: String,
amount: DocDataBigInt,
}

#[on_set_doc]
fn on_set_doc(context: OnSetDocContext) -> Result<(), String> {
let data: Person = decode_doc_data(&context.data.data.after.data)?;

print(format!("Caller: {}", context.caller.to_text()));
print(format!("Data: {}", amount.value));
}
