///
/// This trait allows you to attach a prefix to both the `Ok` and `Err` variants
/// of a `Result`, making it easier to track additional contextual information
/// alongside the original result. It is especially handy when `P` does not implement
/// `Clone` and `Copy`.

	/// Maps this `Result` to a new `Result` with a prefixed value.
