pub struct ExecutionContext { /* private fields */ }Expand description
ExecutionContext 是 JSHandle 的所属上下文(对应 Page 的 isolated world)。
本 TASK 内简化为 ID holder;真实 ExecutionContext 持有
Runtime.executionContextCreated 事件返回的 uniqueId/name/origin/auxData。

self’s address as *mut Self for deferred-task / scopeguard /
ref_guard ctx slots. The closures/trampolines deref it as shared
(&*p) — every method they reach is &self post-R-2, so no write
provenance is required; the *mut spelling is purely to match the
existing DerefOnDrop / HasAutoFlush / RefCount ABI.Source§impl<T> BorrowMut<T> for Twhere
