Functions
std::array< double, 4 >	openswmm::surface::snowRuntimeForcing (const SimulationContext &context)
	Read the small runtime override key used to invalidate held predictions.
bool	openswmm::surface::snowTransientForcing (const SimulationContext &context)
	Test whether temperature or wind has a transient active runtime override.
std::string	openswmm::surface::snowModelIdentity (const SimulationContext &context, const snow::SnowSoA &snow)
	Encode the native snow restart compatibility identity.
std::string	openswmm::surface::snowForcingIdentity (const SimulationContext &context)
	Encode configuration and actual weather values controlling held snow predictions.
void	openswmm::surface::archiveHeldSnow (detail::CompletedSourceArchive &archive, ueb::HeldState &held)
	Stream and validate accepted/predicted lumped UEB history and consumption clocks.
void	openswmm::surface::archiveDegreeDaySnow (detail::CompletedSourceArchive &archive, snow::SnowSoA &snow)
	Stream fixed-layout native degree-day dynamic state and shared report histories.
std::string	openswmm::surface::saveSnowCheckpoint (const SimulationContext &context, const snow::SnowSoA &snow)
	Encode native degree-day and UEB accepted/held snow state without owner mutation.
std::string	openswmm::surface::restoreSnowCheckpoint (SimulationContext &context, snow::SnowSoA &snow, const std::string &bytes, bool apply=true, bool seed=false)
	Decode native snow into a compatible model, optionally as a new hot start.
std::string	openswmm::surface::saveCombinedSnowCheckpoint (const SimulationContext &context, const snow::SnowSoA &snow, const MeshSnow *mesh)
	Encode native snow and, when active, the paired mesh snow owner.
std::string	openswmm::surface::restoreCombinedSnowCheckpoint (SimulationContext &context, snow::SnowSoA &snow, MeshSnow *mesh, const std::string &bytes, bool apply, bool seed)
	Validate native and mesh snow together before ordinary publication.
