Enum chalk_ir::LifetimeData [−][src]
pub enum LifetimeData<I: Interner> { BoundVar(BoundVar), InferenceVar(InferenceVar), Placeholder(PlaceholderIndex), Static, Empty(UniverseIndex), Erased, Phantom(Void, PhantomData<I>), }
Expand description
Lifetime data, including what kind of lifetime it is and what it points to.
Variants
BoundVar(BoundVar)
See TyKind::BoundVar.
InferenceVar(InferenceVar)
Lifetime whose value is being inferred.
Placeholder(PlaceholderIndex)
Lifetime on some yet-unknown placeholder.
Static lifetime
Empty(UniverseIndex)
An empty lifetime: a lifetime shorter than any other lifetime in a universe with a lesser or equal index. The universe only non-zero in lexical region resolve in rustc, so chalk shouldn’t ever see a non-zero index.
An erased lifetime, used by rustc to improve caching when we doesn’t care about lifetimes
Phantom(Void, PhantomData<I>)
Lifetime on phantom data.
