Function cybergrape::gui::fold_until_stop::fold_until_stop   
source ยท pub fn fold_until_stop<F, T>(init: T, f: F) -> Result<T, GrapeGuiError>Expand description
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.
