Trait SpawnHandle

pub trait SpawnHandle:
    Clone
    + Send
    + 'static {
    // Required methods
    fn spawn(
        &self,
        name: &'static str,
        task: impl Future<Output = ()> + Send + 'static,
    );
    fn spawn_essential(
        &self,
        name: &'static str,
        task: impl Future<Output = ()> + Send + 'static,
    ) -> Pin<Box<dyn Future<Output = Result<(), ()>> + Send>>;
}

An abstraction for an execution engine for Rust’s asynchronous tasks.

Required Methods

fn spawn( &self, name: &'static str, task: impl Future<Output = ()> + Send + 'static, )

Run a new task.

fn spawn_essential( &self, name: &'static str, task: impl Future<Output = ()> + Send + 'static, ) -> Pin<Box<dyn Future<Output = Result<(), ()>> + Send>>

Run a new task and returns a handle to it. If there is some error or panic during execution of the task, the handle should return an error.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
