5/// Represents the outer-level, user-facing errors of the tycho-simulation package.
6///
7/// `SimulationError` encompasses all possible errors that can occur in the package,
8/// wrapping lower-level errors in a user-friendly way for easier handling and display.
9/// Variants:
10/// - `RecoverableError`: Indicates that the simulation has failed with a recoverable error.
11///   Retrying at a later time may succeed. It may have failed due to a temporary issue, such as a
12///   network problem.
13/// - `InvalidInput`: Indicates that the simulation has failed due to bad input parameters.
14/// - `FatalError`: There is a bug with this pool or protocol - do not attempt simulation again.
