Struct ForegroundExecutor 

pub struct ForegroundExecutor { /* private fields */ }

A pointer to the executor that is currently running, for spawning tasks on the main thread.

This is intentionally !Send via the not_send marker field. This is because ForegroundExecutor::spawn does not require Send but checks at runtime that the future is only polled from the same thread it was spawned from. These checks would fail when spawning foreground tasks from from background threads.
