Struct MyWorldPre

Source
pub struct MyWorldPre<T> { /* private fields */ }
Available on crate feature runtime and crate feature component-model and docsrs only.
Expand description

Auto-generated bindings for a pre-instantiated version of a component which implements the world my-world.

This structure is created through MyWorldPre::new which takes a InstancePre that has been created through a Linker.

For more information see MyWorld as well.

Implementations§

Source§

impl<_T> MyWorldPre<_T>

Source

pub fn new(instance_pre: InstancePre<_T>) -> Result<Self>

Creates a new copy of MyWorldPre bindings which can then be used to instantiate into a particular store.

This method may fail if the component behind instance_pre does not have the required exports.

Source

pub fn engine(&self) -> &Engine

Source

pub fn instance_pre(&self) -> &InstancePre<_T>

Source

pub fn instantiate( &self, store: impl AsContextMut<Data = _T>, ) -> Result<MyWorld>

Instantiates a new instance of MyWorld within the store provided.

This function will use self as the pre-instantiated instance to perform instantiation. Afterwards the preloaded indices in self are used to lookup all exports on the resulting instance.
