Function `maybe_err_weighted`

fn maybe_err_weighted<T: Strategy, E: Strategy, impl Into<Probability>: Into<Probability>>(probability_of_err: impl Into<Probability>, t: T, e: E) -> MaybeErr<T, E>

Create a strategy for Results where Ok values are taken from t and Err values are taken from e.

probability_of_ok is the probability (between 0.0 and 1.0, exclusive) that Err is initially chosen.

Generated values shrink to Ok.
