Macro soroban_sdk::contractmeta

contractmeta!() { /* proc-macro */ }

Adds a serialized SCMetaEntry::SCMetaV0 to the WASM contracts custom section under the section name ‘contractmetav0’. Contract developers can use this to append metadata to their contract.

Examples

use soroban_sdk::{contract, contractimpl, contractmeta, vec, symbol_short, BytesN, Env, Symbol, Vec};

contractmeta!(key="desc", val="hello world contract");

#[contract]
pub struct HelloContract;

#[contractimpl]
impl HelloContract {
    pub fn hello(env: Env, to: Symbol) -> Vec<Symbol> {
        vec![&env, symbol_short!("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_short!("Dev"));

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