Trait async_local::AsContext

pub unsafe trait AsContext: AsRef<Context<Self::Target>> {
    type Target: Sync;
}

A marker trait promising AsRef<Context<T>> is implemented in a way that can’t be invalidated

Safety

When assigned to a thread local, the pin drop guarantee must be upheld for Context<T>: it cannot be wrapped in a pointer type nor cell type and it must not be invalidated nor repurposed until when drop happens as a consequence of the thread dropping.
