Struct HelloWorld 

pub struct HelloWorld { /* private fields */ }

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

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

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 HelloWorld::instantiate which only needs a Store, Component, and Linker.

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

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

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

Implementations

impl HelloWorld

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

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

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

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

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

where _T: Send,

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

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

where D: HelloWorldImportsWithStore, for<'a> D::Data<'a>: HelloWorldImports, T: 'static,

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

where D: HelloWorldImportsWithStore, for<'a> D::Data<'a>: HelloWorldImports, T: 'static,

pub fn call_greet<S: AsContextMut>(&self, store: S) -> Result<()>
