Struct AsyncGroup 

pub struct AsyncGroup { /* private fields */ }

Available on crate feature tokio only.

The structure that allows for the concurrent execution of multiple asynchronous tasks using green-thread and waits for all of them to complete.

Functions are added using the add method and are then run concurrently in separate green-threads. The AsyncGroup ensures that all tasks finish before proceeding, and can collect any errors that occur.

Implementations

impl AsyncGroup

pub fn add<Fut>(&mut self, future: Fut)

where Fut: Future<Output = Result<()>> + Send + 'static,

Adds a future to the AsyncGroup to be executed concurrently.

The provided future will be polled along with others in this group.

Parameters

• future - The future to add. It must implement Future<Output = errs::Result<()>>, Send, and have a 'static lifetime.
