Struct InstancePre

source

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

Available on crate features runtime and component-model only.

Expand description

A “pre-instantiated” Instance which has all of its arguments already supplied and is ready to instantiate.

This structure represents an efficient form of instantiation where import type-checking and import lookup has all been resolved by the time that this type is created. This type is primarily created through the Linker::instantiate_pre method.

Implementations§

source §

impl<T> InstancePre<T>

source

pub fn component(&self) -> &Component

Returns the underlying component that will be instantiated.

source

pub fn engine(&self) -> &Engine

Returns the underlying engine.

source

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

Performs the instantiation process into the store specified.

source

pub async fn instantiate_async( &self, store: impl AsContextMut<Data = T>, ) -> Result<Instance>
where T: Send,

Available on crate feature async only.

Performs the instantiation process into the store specified.

Exactly like Self::instantiate except for use on async stores.
