Expand description
This structure is supposed to keep enough data to re-create NameBinding
s for other crates
during name resolution. Right now the bindings are not recreated entirely precisely so we may
need to add more data in the future to correctly support macros 2.0, for example.
Module child can be either a proper item or a reexport (including private imports).
In case of reexport all the fields describe the reexport item itself, not what it refers to.
Fields
ident: Ident
Name of the item.
res: Res<!>
Resolution result corresponding to the item.
Local variables cannot be exported, so this Res
doesn’t need the ID parameter.
vis: Visibility<DefId>
Visibility of the item.
span: Span
Span of the item.
macro_rules: bool
A proper macro_rules
item (not a reexport).

something which is needed when forcing DepNode
s during red-green
evaluation. The query system will only call this method if
fingerprint_style()
is not FingerprintStyle::Opaque
.
It is always valid to return None
here, in which case incremental
compilation will treat the query as having changed instead of forcing it. Read moresourceimpl<T, R> InternIteratorElement<T, R> for T

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.
