Enum rustc_middle::ty::Visibility
source · [−]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.
Invisible
Not visible anywhere in the local crate. This is the visibility of private external items.
Implementations
sourceimpl Visibility
impl Visibility
sourcepub fn is_accessible_from<T: DefIdTree>(self, module: DefId, tree: T) -> bool
pub fn is_accessible_from<T: DefIdTree>(self, module: DefId, tree: T) -> bool
Returns true
if an item with this visibility is accessible from the given block.
sourcepub fn is_at_least<T: DefIdTree>(self, vis: Visibility, tree: T) -> bool
pub fn is_at_least<T: DefIdTree>(self, vis: Visibility, tree: T) -> bool
Returns true
if this visibility is at least as accessible as the given visibility
pub fn is_visible_locally(self) -> bool
pub fn is_public(self) -> bool

default fn fingerprint_style() -> FingerprintStyle
sourcedefault fn to_fingerprint(&self, tcx: Ctxt) -> Fingerprint
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
default fn to_debug_str(&self, Ctxt) -> String
sourcedefault fn recover(Ctxt, &DepNode<<Ctxt as DepContext>::DepKind>) -> Option<T>
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 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 more

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.
