Provides the ability to execute async code from a sync context, without blocking a tokio core thread or busy looping the cpu.
```rust
async fn main() { // we need to ensure we are in the context of a tokio task tokio::task::spawn(async move { // some library api may take a sync callback // but we want to be able to execute async code (|| { let r = tokiosafeblockon::tokiosafeblockon( // async code to poll synchronously async move { // simulate some async work tokio::time::delayfor( std::time::Duration::frommillis(2) ).await;
// return our result
"test"
},
// timeout to allow async execution
std::time::Duration::from_millis(10),
).unwrap();
// note we get the result inline with no `await`
assert_eq!("test", r);
})()
})
.await
.unwrap();
} ```
