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

Static lifetime

Erased

An erased lifetime, used by rustc to improve caching when we doesn’t care about lifetimes

Phantom(VoidPhantomData<I>)

Lifetime on phantom data.

Implementations

Wrap the lifetime data in a lifetime.
