Trait HandleExt 

pub trait HandleExt<T> {
    // Required methods
    fn spawn_traced<F>(&self, f: F) -> JoinHandle<T>
       where F: Future<Output = T> + Send + 'static,
             T: Send + 'static;
    fn spawn_traced_named<S, F>(&self, name: S, f: F) -> JoinHandle<T>
       where S: Into<String>,
             F: Future<Output = T> + Send + 'static,
             T: Send + 'static;
}

Helper trait for providing traced spawning when using Handle.

Required Methods

fn spawn_traced<F>(&self, f: F) -> JoinHandle<T>

where F: Future<Output = T> + Send + 'static, T: Send + 'static,

Spawns a new asynchronous task, returning a JoinHandle for it.

This is meant to be a thin wrapper over task management types like Handle, and provides implicit “tracing” for spawned futures by ensuring that the task is attached to the current tracing span and the current allocation component.

fn spawn_traced_named<S, F>(&self, name: S, f: F) -> JoinHandle<T>

where S: Into<String>, F: Future<Output = T> + Send + 'static, T: Send + 'static,

Spawns a new named asynchronous task, returning a JoinHandle for it.

This is meant to be a thin wrapper over task management types like Handle, and provides implicit “tracing” for spawned futures by ensuring that the task is attached to the current tracing span and the current allocation component.

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.
