Result

Exception used to short circuit a task evaluation with a pretty error string or a Failure object containing metadata for pretty error reporting

Models the kind of error reporting supported by Mill's terminal UI. Apart from the simple error: String, also supports file position and exception stack trace metadata to provide richer error diagnostics, and can be chained together via Failure.join to return multiple failures at once.

An exception that has its original class and metadata replaced by a Failure.ExceptionInfo data structure. Used to sanitize exceptions when propagating them across classloader boundaries, since some of the exceptions in a cause-chain may be instances of no-longer-valid classes after a classloader is closed
