Trait Runtime 

pub trait Runtime:

    + 'static {
    // Required methods
    fn new_timer(&self, i: Instant) -> Pin<Box<dyn AsyncTimer>>;
    fn spawn(&self, future: Pin<Box<dyn Future<Output = ()> + Send>>);
    fn wrap_udp_socket(&self, t: UdpSocket) -> Result<Arc<dyn AsyncUdpSocket>>;

    // Provided method
    fn now(&self) -> Instant { ... }
}

Abstracts I/O and timer operations for runtime independence

Required Methods

fn new_timer(&self, i: Instant) -> Pin<Box<dyn AsyncTimer>>

Construct a timer that will expire at i

fn spawn(&self, future: Pin<Box<dyn Future<Output = ()> + Send>>)

Drive future to completion in the background

fn wrap_udp_socket(&self, t: UdpSocket) -> Result<Arc<dyn AsyncUdpSocket>>

Convert t into the socket type used by this runtime

Provided Methods

fn now(&self) -> Instant

Look up the current time

Allows simulating the flow of time for testing.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
