Module module

A WebAssembly module contains stateless WebAssembly code that has already been compiled and can be instantiated multiple times.

Entry points: A WebAssembly module is created with wasm_module_new and freed with wasm_module_delete.

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);

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

    return 0;
}

Structs

wasm_module_t

Opaque type representing a WebAssembly module.

Functions

wasm_module_delete^⚠

Deletes a WebAssembly module.

wasm_module_deserialize^⚠

Deserializes a serialized module binary into a wasm_module_t.

wasm_module_exports^⚠

Returns an array of the exported types in the module.

wasm_module_imports^⚠

Returns an array of the imported types in the module.

wasm_module_new^⚠

A WebAssembly module contains stateless WebAssembly code that has already been compiled and can be instantiated multiple times.

wasm_module_serialize^⚠

Serializes a module into a binary representation that the engine can later process via wasm_module_deserialize.

wasm_module_validate^⚠

Validates a new WebAssembly module given the configuration in the store.
