Struct Bindings

pub struct Bindings {}

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

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

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

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

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

Implementations

impl Bindings

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

where _T: Send,

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

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

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

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

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