Function rodio::source::from_factory

Important traits for FromIter<I>

impl<I> Iterator for FromIter<I> where
    I: Iterator,
    I::Item: Iterator + Source,
    <I::Item as Iterator>::Item: Sample,  type Item = <I::Item as Iterator>::Item;

pub fn from_factory<F, S>(factory: F) -> FromIter<FromFactoryIter<F>> where
    F: FnMut() -> Option<S>, 

Builds a source that chains sources built from a factory.

The factory parameter is a function that produces a source. The source is then played. Whenever the source ends, factory is called again in order to produce the source that is played next.

If the factory closure returns None, then the sound ends.
