Function wasmer_c_api::wasm_c_api::unstable::module::wasmer_module_set_name

#[no_mangle]
pub unsafe extern "C" fn wasmer_module_set_name(
    module: &mut wasm_module_t,
    name: &wasm_name_t
) -> bool

Unstable non-standard Wasmer-specific API to set the module’s name. The function returns true if the name has been updated, false otherwise.

Example

int main() {
    // Create the engine and the store.
    wasm_engine_t* engine = wasm_engine_new();
    wasm_store_t* store = wasm_store_new(engine);

    // Create a WebAssembly module from a WAT definition.
    wasm_byte_vec_t wat;
    wasmer_byte_vec_new_from_string(&wat, "(module)");
    wasm_byte_vec_t wasm;
    wat2wasm(&wat, &wasm);

    // Create the module.
    wasm_module_t* module = wasm_module_new(store, &wasm);

    // Read the module's name. There is none for the moment.
    {
        wasm_name_t name;
        wasmer_module_name(module, &name);

        assert(name.size == 0);
    }

    // So, let's set a new name.
    {
        wasm_name_t name;
        wasmer_byte_vec_new_from_string(&name, "hello");
        wasmer_module_set_name(module, &name);
    }

    // And now, let's see the new name.
    {
        wasm_name_t name;
        wasmer_module_name(module, &name);

        // It works!
        wasmer_assert_name(&name, "hello");

        wasm_byte_vec_delete(&name);
    }

    // Free everything.
    wasm_module_delete(module);
    wasm_byte_vec_delete(&wasm);
    wasm_byte_vec_delete(&wat);
    wasm_store_delete(store);
    wasm_engine_delete(engine);

    return 0;
}
