Expand description
Single-threaded std-based executor.
Implementations
sourceimpl Executor
impl Executor
sourcepub fn run(&'static mut self, init: impl FnOnce(Spawner)) -> !
pub fn run(&'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 withtransmute
. (unsafe)
This function never returns.
