Cancellation

Executing an QIO returns a cancel callback. Essentially a function that when called, aborts the IO from any further execution and releases all the acquired resources.

Create an QIO

+ import {QIO} from '@qio/core'
+
+ const delayIO = QIO.timeout('Hello World', 1000)

Execute by passing it to defaultRuntime

- import {QIO} from '@qio/core'
+ import {QIO, defaultRuntime} from '@qio/core'

  const delayIO = QIO.timeout('Hello World', 1000)
+ const cancel = defaultRuntime().unsafeExecute(delayIO)

Calling the cancelling callback.

  import {QIO, defaultRuntime} from '@qio/core'
  const delayIO = QIO.timeout('Hello World', 1000)
  const cancel = defaultRuntime().execute(delayIO)

+ cancel()

As soon as cancel is called internally the timeout is cancelled.
