Expand description

Everything you need to know about a name’s location to resolve it. Serves as a starting point for the scope visitor. This struct is currently used only for early resolution (imports and macros), but not for late resolution yet.

## Fields§

### impl<'a> ParentScope<'a>

source

#### pub(crate) fn module( module: Module<'a>, resolver: &Resolver<'a, '_> ) -> ParentScope<'a>

## Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain `repr(...)` attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
