Struct Executor

pub struct Executor { /* private fields */ }

WASM executor, wasm_bindgen to schedule tasks on the JS event loop.

Implementations

impl Executor

pub fn new() -> Self

Create a new Executor.

pub fn start(&'static mut self, init: impl FnOnce(Spawner))

Run the executor.

The init closure is called with a Spawner that spawns tasks on this executor. Use it to spawn the initial task(s). After init returns, the executor starts running the tasks.

To spawn more tasks later, you may keep copies of the Spawner (it is Copy), for example by passing it as an argument to the initial tasks.

This function requires &'static mut self. This means you have to store the Executor instance in a place where it’ll live forever and grants you mutable access. There’s a few ways to do this:

• a StaticCell (safe)
• a static mut (unsafe)
• a local variable in a function you know never returns (like fn main() -> !), upgrading its lifetime with transmute. (unsafe)
