Struct Async

pub struct Async<T> { /* private fields */ }

A wrapper type around some “handle” that we want to perform asynchronous operations on, where that handle must implement AsyncSetup.

Implementations

impl<T: AsyncSetup> Async<T>

pub fn new(handle: T) -> Self

Construct a new Async.

pub fn get_ref(&self) -> &T

Return a reference to the underlying handle.

pub fn into_inner(self) -> T

Consume this Async and return the handle.

pub async fn run_with<R>( &self, op: impl FnMut(&T) -> Result<R, T::Error>, ) -> Result<R, T::Error>

Asynchronously run an operation that will sleep if not ready. The closure to run must return Result<_, T::Error>, and should return Err(T::WOULD_BLOCK) if the operation is not ready.

Trait Implementations

impl<T: Debug> Debug for Async<T>

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

Formats the value using the given formatter.

impl<T> Drop for Async<T>

fn drop(&mut self)

Executes the destructor for this type.
