Classes
struct	pulp::platform::DeviceCapabilityInputs
	What a shell observed about the device it is running on. More...

Namespaces
namespace	pulp
namespace	pulp::platform
	Device capability vocabulary: one tier ladder, one thermal ladder, and the projection from observed inputs onto them.
namespace	pulp::platform::detail

Enumerations
enum class	pulp::platform::DeviceCapabilityTier : std::uint8_t { pulp::platform::Constrained = 0 , pulp::platform::Standard = 1 , pulp::platform::Full = 2 }
	How much of the product a device can carry, on one ascending ladder. More...
enum class	pulp::platform::ThermalState : std::uint8_t { pulp::platform::Nominal = 0 , pulp::platform::Fair = 1 , pulp::platform::Serious = 2 , pulp::platform::Critical = 3 }
	Live thermal pressure, ascending in heat. More...
enum class	pulp::platform::PointerPrecision : std::uint8_t { pulp::platform::Coarse = 0 , pulp::platform::Fine = 1 }
	Precision of the device's primary pointing device. More...

Functions
constexpr DeviceCapabilityTier	pulp::platform::detail::min_tier (DeviceCapabilityTier left, DeviceCapabilityTier right)
	Returns the lower of two tiers.
constexpr DeviceCapabilityTier	pulp::platform::project_device_capability_tier (DeviceCapabilityInputs inputs)
	Projects observed capabilities onto the tier ladder.
