Struct rustc_resolve::ParentScope
source · pub(crate) struct ParentScope<'a> {

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§
§module: Module<'a>
§expansion: LocalExpnId
§macro_rules: Interned<'a, Cell<MacroRulesScope<'a>>>
§derives: &'a [Path]

resolver: &Resolver<'a, '_>
) -> ParentScope<'a>
pub(crate) fn module( module: Module<'a>, resolver: &Resolver<'a, '_> ) -> ParentScope<'a>
Creates a parent scope with the passed argument used as the module scope component, and other scope components set to default empty values.

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.
