Struct AsyncContext

Source 
pub struct AsyncContext<C, T, F>
where
    C: 'static,
    F: Future<Output = T>,
{ /* private fields */ }
Expand description

Stores a future along with the async context provided for it. Create AsyncContext using provide_async_context Access the context using with_async_context or with_async_context_mut
