Function cybergrape::gui::fold_until_stop

pub fn fold_until_stop<F, T>(init: T, f: F) -> Result<T, GrapeGuiError>
where
    F: Fn(T) -> T + Send + Sync + 'static,
    T: Send + Sync + 'static,

Generates a gui that runs a function until the user provides input.

The function can be thought of as a recursive fold. init contains the inital state of the loop, then f is called on the inital state to produce a new state, and then f is called on that new state, and so on until the user indicates that this should stop.
