Ganeti.OpParams

Contents

Description

Implementation of opcodes parameters.

These are defined in a separate module only due to TemplateHaskell stage restrictions - expressions defined in the current module can't be passed to splices. So we have to either parameters/repeat each parameter definition multiple times, or separate them into this module.
