Struct rustc_middle::metadata::ModChild
source · [−]pub struct ModChild {
pub ident: Ident,
pub res: Res<!>,
pub vis: Visibility,
pub span: Span,
}Expand description
This structure is supposed to keep enough data to re-create NameBindings 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: IdentName 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: VisibilityVisibility of the item.
span: SpanSpan of the item.

This method turns the parameters of a DepNodeConstructor into an opaque Fingerprint to be used in DepNode. Not all DepNodeParams support being turned into a Fingerprint (they don’t need to if the corresponding DepNode is anonymous). Read more
This method tries to recover the query key from the given DepNode,
something which is needed when forcing DepNodes 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 more
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.
