Module task

task module provides helper functions for use with async closures that operate uniformly in native (tokio-backed) and WASM (async_std-backed) environments (i.e. a web browser).

Following functions are are available:

• spawn() - non-blocking spawn of the supplied async closure
• sleep() - suspends the task for a given Duration
• yield_now() - yields rust executor
• yield_executor() - yields to top-level executor (browser async loop)

Blocking spawn is not available as a part of this framework as WASM-browser environment can
not block task execution due to a single-threaded async application environment.

Modules

wasm

WASM implementation

Macros

call_async_no_send

Structs

Interval

Interval stream used by the interval() function to provide a a time interval stream. The stream is backed by tokio interval stream on native platforms and by by the JavaScript setInterval() and clearInterval() APIs in WASM32 environment.

Functions

dispatch

interval

async interval() function backed by the JavaScript createInterval()

sleep

Waits until duration has elapsed.

spawn

yield_executor

Yields execution back to the Tokio runtime.

yield_now

Yields execution back to the Tokio runtime.
