A minimalist generic single-threaded queue that aggregates results and populates the queue with more tasks.
Pass the first job that should be run as the first parameter.
The second parameter is a function that receives the job and executes, and then returns a tuple containing:
All the jobs returned in the vector will be enqueued to be ran later. Notice that jobs that were already ran in the past will not be scheduled again.
The end result of run is a HashMap aggregating jobs and job results.
Both the job and job result are generic types.
```rust use miniqueue;
let result = run(1, |num| { match num { 1 => Ok(("one", vec![ 2 ])), 2 => Ok(("two", vec![])), _ => Ok(("", vec![])) } });
assert_eq!(result.unwrap().get(&1), Some(&"one")); ```
