Struct Worker

pub struct Worker { /* private fields */ }

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

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 Worker::instantiate_async which only needs a Store, Component, and Linker.

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

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

• You can also access the guts of instantiation through WorkerIndices::new_instance followed by WorkerIndices::load to crate an instance of this type.

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

Implementations

impl Worker

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

where _T: Send,

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

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

Convenience wrapper around WorkerIndices::new_instance and WorkerIndices::load.

pub fn add_to_linker<T, U>( linker: &mut Linker<T>, get: impl Fn(&mut T) -> &mut U + Send + Sync + Copy + 'static, ) -> Result<()>

where T: Send, U: Host + Host + Host + Host + Host + Host + Host + Host + Send,

pub async fn call_init<S: AsContextMut>( &self, store: S, arg0: &Config, ) -> Result<()>

where <S as AsContext>::Data: Send,

pub async fn call_handle<S: AsContextMut>( &self, store: S, arg0: u32, arg1: &Event, ) -> Result<Result<Response, HandleError>>

where <S as AsContext>::Data: Send,
