Struct actix_rt::Runtime [−][src]
A Tokio-based runtime proxy.
All spawned futures will be executed on the current thread. Therefore, there is no Send
bound
on submitted futures.
Implementations
impl Runtime
[src]
pub fn new() -> Result<Self>
[src]
Returns a new runtime initialized with default configuration values.
pub fn spawn<F>(&self, future: F) -> JoinHandle<F::Output>ⓘNotable traits for JoinHandle<T>
impl<T> Future for JoinHandle<T> type Output = Result<T, JoinError>;
where
F: Future + 'static,
[src]
Notable traits for JoinHandle<T>
impl<T> Future for JoinHandle<T> type Output = Result<T, JoinError>;
F: Future + 'static,
Offload a future onto the single-threaded runtime.
The returned join handle can be used to await the future's result.
See crate root documentation for more details.
Examples
let rt = actix_rt::Runtime::new().unwrap(); // Spawn a future onto the runtime let handle = rt.spawn(async { println!("running on the runtime"); 42 }); assert_eq!(rt.block_on(handle).unwrap(), 42);
Panics
This function panics if the spawn fails. Failure occurs if the executor is currently at capacity and is unable to spawn a new future.
pub fn block_on<F>(&self, f: F) -> F::Output where
F: Future,
[src]
F: Future,
Runs the provided future, blocking the current thread until the future completes.
This function can be used to synchronously block the current thread until the provided
future
has resolved either successfully or with an error. The result of the future is
then returned from this function call.
Note that this function will also execute any spawned futures on the current thread, but
will not block until these other spawned futures have completed. Once the function returns,
any uncompleted futures remain pending in the Runtime
instance. These futures will not run
until block_on
or run
is called again.
The caller is responsible for ensuring that other spawned futures complete execution by
calling block_on
or run
.
