Struct wasmcloud_runtime::capability::Interfaces

pub struct Interfaces {}

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

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

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

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

• You can also access the guts of instantiation through [InterfacesIndices::new_instance] followed by [InterfacesIndices::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 Interfaces

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

where _T: Send,

Convenience wrapper around [InterfacesPre::new] and [InterfacesPre::instantiate_async].

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

Convenience wrapper around [InterfacesIndices::new_instance] and [InterfacesIndices::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 + Host + Host + Host + Host + Host + Host + Host + Host + Host + Send,
