Enum rustc_resolve::ScopeSet[−][src]

pub(crate) enum ScopeSet<'a> {
    All(Namespace, bool),
    AbsolutePath(Namespace),
    Macro(MacroKind),
    Late(Namespace, &'a ModuleData<'a>, Option<NodeId>),
}
Expand description

Names from different contexts may want to visit different subsets of all specific scopes with different restrictions when looking up the resolution. This enum is currently used only for early resolution (imports and macros), but not for late resolution yet.

Variants

All(Namespace, bool)
Expand description

All scopes with the given namespace.

AbsolutePath(Namespace)
Expand description

Crate root, then extern prelude (used for mixed 2015-2018 mode in macros).

Macro(MacroKind)
Expand description

All scopes with macro namespace and the given macro kind restriction.

Late(Namespace, &'a ModuleData<'a>, Option<NodeId>)
Expand description

All scopes with the given namespace, used for partially performing late resolution. The node id enables lints and is used for reporting them.
