pub struct Executor { /* private fields */ }
Expand description

Single-threaded std-based executor.

Implementations

Create a new Executor.

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)

This function never returns.
