Records

Functions

  • std::vector<int64_t> GetTimestamps (const inspect::Hierarchy * history_hierarchy, size_t count)

    Extracts timestamps from a "history" hierarchy.

    Defined at line 32 of file ../../sdk/lib/power/state_recorder/cpp/tests/state_recorder_test.cc

  • int64_t GetCurrentTimestamp (bool lazy_record)

    Returns the current timestamp in nanoseconds, clamped to millisecond resolution if `lazy_record`

    is true.

Concepts

template <typename T> WidensToUint32 std::is_same_v<T, _Bool> || std::is_same_v<T, uint8_t> || std::is_same_v<T, uint16_t> || std::is_same_v<T, uint32_t>

The concepts below, combined with a few natural types, specify the numeric types that can be

used with NumericStateRecorder and how they are recorded to trace and Inspect.

| Concept | Trace type | Inspect type |

|----------------|------------|--------------|

| WidensToUint32 | uint32_t | uint64_t |

| uint64_t | uint64_t | uint64_t |

| WidensToInt32 | int32_t | int64_t |

| int64_t | int64_t | int64_t |

| WidensToDouble | double | double |

template <typename T> IsRecordableEnumType std::is_enum_v<T> && (WidensToUint64<std::underlying_type_t<T> > || WidensToInt64<std::underlying_type_t<T> >)

An enum type is recordable if it can be mapped in an obvious way to Inspect.
