Variants

Import

An imported item is required to be provided.

Fields of Import

module: String

Module name of this import

field: Option<String>

Optional field name of this import

index: EntityIndex

Where this import will be placed, which also has type information about the import.

AliasParentModule(ModuleIndex)

A module from the parent’s declared modules is inserted into our own index space.

AliasInstanceExport

A module from the parent’s declared modules is inserted into our own index space.

Fields of AliasInstanceExport

instance: InstanceIndexexport: usize

Instantiate

A module is being instantiated with previously configured intializers as arguments.

Fields of Instantiate

module: ModuleIndex

The module that this instance is instantiating.

args: Vec<EntityIndex>

The arguments provided to instantiation.

DefineModule(usize)

A module is defined into the module index space, and which module is being defined is specified by the index payload.
