Struct App 

pub struct App { /* private fields */ }

Available on crate feature component-model and crate feature runtime and (docsrs) only.

Auto-generated bindings for an instance a component which implements the world app.

This structure can be created through a number of means depending on your requirements and what you have on hand:

• The most convenient way is to use App::instantiate which only needs a Store, Component, and Linker.

• Alternatively you can create a AppPre ahead of time with a Component to front-load string lookups of exports once instead of per-instantiation. This method then uses AppPre::instantiate to create a App.

• If you’ve instantiated the instance yourself already then you can use App::new.

These methods are all equivalent to one another and move around the tradeoff of what work is performed when.

Implementations

impl App

pub fn instantiate<_T>( store: impl AsContextMut<Data = _T>, component: &Component, linker: &Linker<_T>, ) -> Result<App>

Convenience wrapper around AppPre::new and AppPre::instantiate.

pub fn new(store: impl AsContextMut, instance: &Instance) -> Result<App>

Convenience wrapper around AppIndices::new and AppIndices::load.

pub async fn instantiate_async<_T>( store: impl AsContextMut<Data = _T>, component: &Component, linker: &Linker<_T>, ) -> Result<App>

where _T: Send,

Convenience wrapper around AppPre::new and AppPre::instantiate_async.

pub fn add_to_linker<T, D>( linker: &mut Linker<T>, host_getter: fn(&mut T) -> D::Data<'_>, ) -> Result<()>

where D: HostWithStore<T> + Send, for<'a> D::Data<'a>: Host + Send, T: 'static + Send,

pub fn func_run(&self) -> TypedFunc<(), ()>

pub async fn call_run<_T, _D>(&self, accessor: &Accessor<_T, _D>) -> Result<()>

where _T: Send, _D: HasData,

Because logging.logger.log is async, run must also be async; otherwise, a trap will occur at runtime if run calls log and it blocks.
