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.

• You can also access the guts of instantiation through BindingsIndices::new_instance followed by BindingsIndices::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 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_instance and BindingsIndices::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 + Send,
