Enum rustc_resolve::ScopeSet
source · pub(crate) enum ScopeSet<'a> {
All(Namespace),
AbsolutePath(Namespace),
Macro(MacroKind),
Late(Namespace, Module<'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)
All scopes with the given namespace.
AbsolutePath(Namespace)
Crate root, then extern prelude (used for mixed 2015-2018 mode in macros).
Macro(MacroKind)
All scopes with macro namespace and the given macro kind restriction.
Late(Namespace, Module<'a>, Option<NodeId>)
All scopes with the given namespace, used for partially performing late resolution. The node id enables lints and is used for reporting them.

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.
