A trait for implementing the low-level operations needed to load an App.

Required Methods

fn load_app<'life0, 'life1, 'async_trait>(
    &'life0 self,
    uri: &'life1 str
) -> Pin<Box<dyn Future<Output = Result<LockedApp>> + Send + 'async_trait>>where
    Self: 'async_trait,
    'life0: 'async_trait,
    'life1: 'async_trait,

Called with an implementation-defined uri pointing to some representation of a LockedApp, which will be loaded.

fn load_module<'life0, 'life1, 'life2, 'async_trait>(
    &'life0 self,
    engine: &'life1 Engine,
    source: &'life2 LockedComponentSource
) -> Pin<Box<dyn Future<Output = Result<Module>> + Send + 'async_trait>>where
    Self: 'async_trait,
    'life0: 'async_trait,
    'life1: 'async_trait,
    'life2: 'async_trait,

Called with a LockedComponentSource pointing to a Wasm module binary, which will be loaded.

fn mount_files<'life0, 'life1, 'life2, 'async_trait>(
    &'life0 self,
    store_builder: &'life1 mut StoreBuilder,
    component: &'life2 AppComponent<'_>
) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>where
    Self: 'async_trait,
    'life0: 'async_trait,
    'life1: 'async_trait,
    'life2: 'async_trait,

Called with an AppComponent; any files configured with the component should be “mounted” into the store_builder, via e.g. StoreBuilder::read_only_preopened_dir.
