Variants

OuterModule

An outer module’s module is being aliased into our own index space.

Fields of OuterModule

relative_depth: u32

The number of modules above us that we’re referencing.

index: ModuleIndex

The module index in the outer module’s index space we’re referencing.

OuterType

An outer module’s type is being aliased into our own index space

Note that the index here is in the outer module’s index space, not our own.

Fields of OuterType

relative_depth: u32

The number of modules above us that we’re referencing.

index: TypeIndex

The type index in the outer module’s index space we’re referencing.

InstanceExport

A previously created instance is having one of its exports aliased into our index space.

Fields of InstanceExport

instance: InstanceIndex

The index we’re aliasing.

export: &'a str

The nth export that we’re inserting into our own index space locally.
