Attribute Macro soroban_sdk::contractimpl

#[contractimpl]

Exports the publicly accessible functions to the Soroban environment.

Functions that are publicly accessible in the implementation are invocable by other contracts, or directly by transactions, when deployed.

Examples

Define a contract with one function, hello, and call it from within a test using the generated client.

use soroban_sdk::{contractimpl, symbol, vec, BytesN, Env, Symbol, Vec};

pub struct HelloContract;

#[contractimpl]
impl HelloContract {
    pub fn hello(env: Env, to: Symbol) -> Vec<Symbol> {
        vec![&env, symbol!("Hello"), to]
    }
}

#[test]
fn test() {
    let env = Env::default();
    let contract_id = env.register_contract(None, HelloContract);
    let client = HelloContractClient::new(&env, &contract_id);

    let words = client.hello(&symbol!("Dev"));

    assert_eq!(words, vec![&env, symbol!("Hello"), symbol!("Dev"),]);
}
