Function parallelize

pub fn parallelize<T, F>(
    thread_pool: &mut ThreadPool,
    data: &mut [T],
    func: F,
) -> usize
where
    T: Sync,
    F: Sync + Fn(&mut [T], usize),

Runs the function on multiple threads, splitting the data into one part for each thread.

The function also gets the offset of the specific subslice it got, relative to the start of data.

The return value is the size of the chunks data was split into. The same slices can be acquired by calling chunks or chunks_mut on data and passing it in as the chunk size. If the input slice is empty, 0 is returned.

Panics

If the thread pool already has pending tasks. This shouldn’t ever be the case when using the threadpool with just this function, as this function always consumes all tasks it spawns.
