key_value_iterable.h Supports internal iteration over a collection of key-value pairs. 1997 100 %
key_value_iterable_view.h @brief Container for key-value pairs that can transform every value in it to one of types listed in common::AttributeValue. It may contain value types that are not directly map'able to primitive value types. In that case the `ForEachKeyValue` method acts as a transform to convert the value type to one listed under AtributeValue (bool, int32_t, int64_t, uint32_t, uint64_t, double, nostd::string_view, or arrays of primite types). For example, if UUID, GUID, or UTF-16 string type is passed as one of values stored inside this container, the container itself may provide a custom implementation of `ForEachKeyValue` to transform the 'non-standard' type to one of the standard types. 4985 58 %

macros.h OPENTELEMETRY_HAVE_BUILTIN&OPENTELEMETRY_HAVE_FEATURE Checks whether the compiler supports a Clang Feature Checking Macro, and if so, checks whether it supports the provided builtin function "x" where x is one of the functions noted in https://clang.llvm.org/docs/LanguageExtensions.html Note: Use this macro to avoid an extra level of #ifdef __has_builtin check. http://releases.llvm.org/3.3/tools/clang/docs/LanguageExtensions.html 18540 -
spin_lock_mutex.h A Mutex which uses atomic flags and spin-locks instead of halting threads. This mutex uses an incremental back-off strategy with the following phases: 1. A tight spin-lock loop (pending: using hardware PAUSE/YIELD instructions) 2. A loop where the current thread yields control after checking the lock. 3. Issuing a thread-sleep call before starting back in phase 1. This is meant to give a good balance of perofrmance and CPU consumption in practice.
