Struct WithImports

pub struct WithImports {}

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 with-imports.

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

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

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

• You can also access the guts of instantiation through WithImportsIndices::new_instance followed by WithImportsIndices::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 WithImports

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

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

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

Convenience wrapper around WithImportsIndices::new_instance and WithImportsIndices::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 U: Host,
