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

Handle to spawn tasks into an executor.

This Spawner can spawn any task (Send and non-Send ones), but it can only be used in the executor thread (it is not Send itself).

If you want to spawn tasks from another thread, use SendSpawner.

Implementations§

source§

impl Spawner

source

pub async fn for_current_executor() -> Self

Get a Spawner for the current executor.

This function is async just to get access to the current async context. It returns instantly, it does not block/yield.

§Panics

Panics if the current executor is not an Embassy executor.

source

pub fn spawn<S>(&self, token: SpawnToken<S>) -> Result<(), SpawnError>

Spawn a task into an executor.

You obtain the token by calling a task function (i.e. one marked with #[embassy_executor::task]).

source

pub fn must_spawn<S>(&self, token: SpawnToken<S>)

Spawn a task into an executor, panicking on failure.

§Panics

Panics if the spawning fails.

source

pub fn make_send(&self) -> SendSpawner

Convert this Spawner to a SendSpawner. This allows you to send the spawner to other threads, but the spawner loses the ability to spawn non-Send tasks.
