Enum rustc_middle::ty::Visibility[−][src]

pub enum Visibility {
    Public,
    Restricted(DefId),
    Invisible,
}

Variants

Public

Visible everywhere (including in other crates).

Restricted(DefId)

Visible only in the given crate-local module.

Tuple Fields of Restricted

0: DefId

Invisible

Not visible anywhere in the local crate. This is the visibility of private external items.

impl<Ctxt, T> DepNodeParams<Ctxt> for T where
Ctxt: DepContext,

[src]

pub default fn fingerprint_style() -> FingerprintStyle

[src]

pub default fn to_fingerprint(&self, tcx: Ctxt) -> Fingerprint

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

[src]

pub default fn to_debug_str(&self, Ctxt) -> String

[src]

pub default fn recover(
Ctxt,
&DepNode<<Ctxt as DepContext>::DepKind>
) -> Option<T>

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
