Variants

Module(&'a ModuleData<'a>)

Regular module.

CrateRootAndExternPrelude

Virtual module that denotes resolution in crate root with fallback to extern prelude.

ExternPrelude

Virtual module that denotes resolution in extern prelude. Used for paths starting with :: on 2018 edition.

CurrentScope

Virtual module that denotes resolution in current scope. Used only for resolving single-segment imports. The reason it exists is that import paths are always split into two parts, the first of which should be some kind of module.
