Struct rustc_resolve::ParentScope

pub struct ParentScope<'a> {
    module: &'a ModuleData<'a>,
    expansion: ExpnId,
    macro_rules: PtrKey<'a, Cell<MacroRulesScope<'a>>>,
    derives: &'a [Path],
}

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: &'a ModuleData<'a>

expansion: ExpnId

macro_rules: PtrKey<'a, Cell<MacroRulesScope<'a>>>

derives: &'a [Path]

Implementations

impl<'a> ParentScope<'a>

pub fn module(
    module: &'a ModuleData<'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.
