Detailed Description

What a shell observed about the device it is running on.

Every field is something a shell can measure. Nothing here is a form factor, an OS name, or a browser name: a caller that knows only "this is a phone" cannot fill this in, which is the point.

Member Data Documentation

pointer_precision

PointerPrecision pulp::platform::DeviceCapabilityInputs::pointer_precision = PointerPrecision::Coarse

Precision of the primary pointer.

precision_keyboard_available

bool pulp::platform::DeviceCapabilityInputs::precision_keyboard_available = false

Whether a physical keyboard with modifier keys is attached.

realtime_render_available

bool pulp::platform::DeviceCapabilityInputs::realtime_render_available = false

Whether a realtime render path — a dedicated audio callback fed across a shared memory region — can be constructed at all.

This is the neutral form of a lane-specific fact. A browser shell folds its own isolation, shared-buffer, and worklet-module observations into this one boolean before calling; a native shell sets it directly. The per-lane spellings stay in the shell that observed them, so this header never has to learn any of them.

thermal_reporting_available

bool pulp::platform::DeviceCapabilityInputs::thermal_reporting_available = false

Whether the platform will report thermal pressure at all.

A device that cannot say it is hot cannot be trusted with the quotas that assume it will say so.

usable_core_count

std::uint32_t pulp::platform::DeviceCapabilityInputs::usable_core_count = 0

Cores available to this process for sustained work.

usable_memory_bytes

std::uint64_t pulp::platform::DeviceCapabilityInputs::usable_memory_bytes = 0

Memory the process may actually use, not the memory the device has installed.

A browser tab's budget and an app's jetsam limit both belong here rather than the hardware figure.
