Trait Implementations

impl Blocking for SmolRuntime

type ThreadHandle<T: Send + 'static> = Task<T>

Future from spawn_blocking

fn spawn_blocking<F, T>(&self, f: F) -> Task<T>

where F: FnOnce() -> T + Send + 'static, T: Send + 'static,

Spawn a thread for blocking IO or CPU-bound work.

fn reenter_block_on<F: Future>(&self, f: F) -> F::Output

Block on a future, from within Blocking::spawn_blocking

fn blocking_io<F, T>(&self, f: F) -> impl Future<Output = T>

where F: FnOnce() -> T + Send + 'static, T: Send + 'static,

Perform some blocking IO from an async future

impl Clone for SmolRuntime

fn clone(&self) -> SmolRuntime

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl NetStreamProvider<SocketAddr> for SmolRuntime

type Stream = UnixStream

The type for the connections returned by Self::connect().

type Listener = UnixListener

The type for the listeners returned by Self::listen().

fn connect<'life0, 'life1, 'async_trait>( &'life0 self, addr: &'life1 SocketAddr, ) -> Pin<Box<dyn Future<Output = IoResult<Self::Stream>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Launch a connection connection to a given socket address.

fn listen<'life0, 'life1, 'async_trait>( &'life0 self, addr: &'life1 SocketAddr, ) -> Pin<Box<dyn Future<Output = IoResult<Self::Listener>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Open a listener on a given socket address.

impl NetStreamProvider for SmolRuntime

type Stream = TcpStream

The type for the connections returned by Self::connect().

type Listener = TcpListener

The type for the listeners returned by Self::listen().

fn connect<'life0, 'life1, 'async_trait>( &'life0 self, addr: &'life1 SocketAddr, ) -> Pin<Box<dyn Future<Output = IoResult<Self::Stream>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Launch a connection connection to a given socket address.

fn listen<'life0, 'life1, 'async_trait>( &'life0 self, addr: &'life1 SocketAddr, ) -> Pin<Box<dyn Future<Output = IoResult<Self::Listener>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Open a listener on a given socket address.

impl SleepProvider for SmolRuntime

type SleepFuture = Pin<Box<dyn Future<Output = ()> + Send>>

A future returned by SleepProvider::sleep()

fn sleep(&self, duration: Duration) -> Self::SleepFuture

Return a future that will be ready after duration has elapsed.

fn now(&self) -> Instant

Return the SleepProvider’s view of the current instant.

fn wallclock(&self) -> SystemTime

Return the SleepProvider’s view of the current wall-clock time.

fn block_advance<T: Into<String>>(&self, _reason: T)

Signify that a test running under mock time shouldn’t advance time yet, with a given unique reason string. This is useful for making sure (mock) time doesn’t advance while things that might require some (real-world) time to complete do so, such as spawning a task on another thread.

fn release_advance<T: Into<String>>(&self, _reason: T)

Signify that the reason to withhold time advancing provided in a call to block_advance no longer exists, and it’s fine to move time forward if nothing else is blocking advances.

fn allow_one_advance(&self, _dur: Duration)

Allow a test running under mock time to advance time by the provided duration, even if the above block_advance API has been used.

impl Spawn for SmolRuntime

fn spawn_obj(&self, future: FutureObj<'static, ()>) -> Result<(), SpawnError>

Spawns a future that will be run to completion.

fn status(&self) -> Result<(), SpawnError>

Determines whether the executor is able to spawn new tasks.

impl ToplevelBlockOn for SmolRuntime

fn block_on<F: Future>(&self, f: F) -> F::Output

Run future until it is ready, and return its output.

impl UdpProvider for SmolRuntime

type UdpSocket = UdpSocket

The type of Udp Socket returned by Self::bind()

fn bind<'life0, 'life1, 'async_trait>( &'life0 self, addr: &'life1 SocketAddr, ) -> Pin<Box<dyn Future<Output = IoResult<Self::UdpSocket>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Bind a local port to send and receive packets from
