Struct Label

#[repr(transparent)]
pub struct Label<Tag: WithLt<L>, L: LifetimeList = L0>(pub <Tag as WithLt<L>>::Reified);

Expand description

Wrapper that reports as being tagged by a specific tag.

Not all types implement Tagged. This wrapper can be used in those cases to have a type that with reify to itself after using it’s tag.
