pub struct Engine<T> { /* private fields */ }
Expand description
Do heavy work in the background.
An engine takes items of work from a work queue, and does the work
in the background, using tokio
blocking tasks. The background
work can be CPU intensive or block on I/O. The number of active
concurrent tasks is limited to the size of the queue.
The actual work is done in a function or closure passed in as a parameter to the engine. The worker function is called with a work item as an argument, in a thread dedicated for that worker function.
The need to move work items between threads puts some restrictions on the types used as work items.
