Struct FalliblePreference 

pub struct FalliblePreference<F, E>
where
    F: Fn(&[f64]) -> Result<f64, E>,
{ /* private fields */ }

Consumer preference backed by a fallible utility function.

This variant is intended for frontends that need utility evaluation to return errors instead of assuming the utility function is infallible.
