Trait Task 

pub trait Task: Future<Output = ()> {
    // Required method
    fn cancel<'async_trait>(
        self: Box<Self>,
    ) -> Pin<Box<dyn Future<Output = Option<()>> + 'async_trait>>
       where Self: 'async_trait;
}

A common interface to wait for a Task completion, let it run n the background or cancel it.

Required Methods

fn cancel<'async_trait>( self: Box<Self>, ) -> Pin<Box<dyn Future<Output = Option<()>> + 'async_trait>>

where Self: 'async_trait,

Cancels the task and waits for it to stop running.

Returns the task’s output if it was completed just before it got canceled, or None if it didn’t complete.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
