Overview

Main class of all Quickl’s errors.

Quickl’s errors normally occur only in the context of a command execution, command which can be obtained through the dedicated accessor.

Each Quickl error comes bundled with a default reaction implemented by the react! method. Unless you provide your own reaction via dedicated Command’s DSL methods (react_to, no_react_to, …), this reaction will be executed if the error is raised. Default reactions are implemented so that the command fail gracefully for the ordinary commandline user.
