Struct ntex::rt::Runtime

pub struct Runtime { /* fields omitted */ }

Single-threaded runtime provides a way to start reactor and runtime on the current thread.

See module level documentation for more details.

Implementations

impl Runtime

pub fn new() -> Result<Runtime, Error>

Returns a new runtime initialized with default configuration values.

pub fn spawn<F>(&self, future: F) -> &Runtime where
    F: Future<Output = ()> + 'static, 

Spawn a future onto the single-threaded runtime.

See module level documentation for more details.

Examples

use ntex_rt::Runtime;

// Create the runtime
let mut rt = Runtime::new().unwrap();

// Spawn a future onto the runtime
rt.spawn(future::lazy(|_| {
    println!("running on the runtime");
}));

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 as Future>::Output where
    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.

Trait Implementations

impl Debug for Runtime

pub fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.
