pub struct GenerationGuard { /* private fields */ }Expand description
The generation counter that makes stale asynchronous work harmless.
Every speculative task records the generation it was started at; before publishing a result it re-reads the counter, and abandons the result if the world has moved on. Without this, a slow retrieval for turn 4 could overwrite the prepared context for turn 5.
