Struct HelloWorldPre

pub struct HelloWorldPre<T> { /* private fields */ }

Available on crate feature runtime and crate feature component-model and docsrs only.

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

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

For more information see HelloWorld as well.

Implementations

impl<_T> HelloWorldPre<_T>

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

Creates a new copy of HelloWorldPre 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.

pub fn engine(&self) -> &Engine

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

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

Instantiates a new instance of HelloWorld 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.

Trait Implementations

impl<T> Clone for HelloWorldPre<T>

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
