Struct SpawnedTask

Source

pub struct SpawnedTask<R> { /* private fields */ }

Expand description

Helper that provides a simple API to spawn a single task and join it. Provides guarantees of aborting on Drop to keep it cancel-safe.

Technically, it’s just a wrapper of JoinSet (with size=1).

Implementations§

impl<R> SpawnedTask<R>
where R: 'static,

Source

pub fn spawn<T>(task: T) -> SpawnedTask<R>
where T: Future<Output = R> + Send + 'static, R: Send,

Available on crate feature parquet only.

Source

pub fn spawn_blocking<T>(task: T) -> SpawnedTask<R>

Source

pub async fn join(self) -> Result<R, JoinError>

Available on crate feature parquet only.

Joins the task, returning the result of join (Result<R, JoinError>).

Source

pub async fn join_unwind(self) -> Result<R, JoinError>

Available on crate feature parquet only.

Joins the task and unwinds the panic if it happens.
