InstancePre in wasmtime - Rust

pub struct InstancePre<T> {  }

Available on crate feature runtime only.

Expand description

An instance, pre-instantiation, that is ready to be instantiated.

This structure represents an instance just before it was instantiated, after all type-checking and imports have been resolved. The only thing left to do for this instance is to actually run the process of instantiation.

Note that an InstancePre may not be tied to any particular Store if none of the imports it closed over are tied to any particular Store.

This structure is created through the Linker::instantiate_pre method, which also has some more information and examples.

Source§ Source

Returns a reference to the module that this InstancePre will be instantiating.

Source

Instantiates this instance, creating a new instance within the provided store.

This function will run the actual process of instantiation to completion. This will use all of the previously-closed-over items as imports to instantiate the module that this was originally created with.

For more information about instantiation see Instance::new.

§Panics

Panics if any import closed over by this InstancePre isn’t owned by store, or if store has async support enabled. Additionally this function will panic if the store provided comes from a different Engine than the InstancePre originally came from.

Source

Available on crate feature async only.

Creates a new instance, running the start function asynchronously instead of inline.

For more information about asynchronous instantiation see the documentation on Instance::new_async.

§Panics

Panics if any import closed over by this InstancePre isn’t owned by store, or if store does not have async support enabled.

InstancePre’s clone does not require T: Clone
