-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its

-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or

-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.

-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each

-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

-# CTraces
-
-The [CTraces](https://github.com/calyptia/ctraces) project is a tiny library to create and maintain Traces contexts and provide utilities for data manipulation, including encoding/decoding for compatibility with OpenTelemetry and other formats.
-
-This project is a core library for [Fluent Bit](https://fluentbit.io): agent and aggregator for Observability.
-
-## Build
-
-Clone the repository:
-
-```shell
-git clone https://github.com/calyptia/ctraces
-```
-
-Get into the project directory and retrieve submodules:
-
-```shell
-cd ctraces
-git submodule update --init --recursive --remote
-```
-
-Compile:
-
-```shell
-cd build/
-cmake -DCTR_DEV=on ../
-make
-```
-
-> CTR_DEV flag enables debugging mode, examples and the unit tests
-
-## Usage
-
-In the [examples](examples/) directory, you will find a _simple_ example that describes how to use the API.
-

-# Instructions to run
-
-After building the project with `-CTR_DEV=on`, the example can be found at `build/examples/ctraces-otlp-encoder`
-
-The example encodes a ctraces context to a buffer and sends it to a locally running instance of the [OpenTelemetry Collector](https://opentelemetry.io/docs/collector/). After setting up the collector locally by [following the instructions from their docs](https://opentelemetry.io/docs/collector/getting-started/), you can start the collector with the following config file:
-
-```yaml
-receivers:
-  otlp:
-    protocols:
-      http:
-        endpoint: "0.0.0.0:4318"
-
-exporters:
-  logging:
-    loglevel: debug
-
-service:
-  pipelines:
-    traces:
-      receivers: [otlp]
-      exporters: [logging]
-```
-
-Now you can run the example and see the trace data logged by the collector instance.

- * Definition of inline macros.
- *
- * MPack does not use static inline in header files; only one non-inline definition
- * of each function should exist in the final build. This can reduce the binary size
- * in cases where the compiler cannot or chooses not to inline a function.
- * The addresses of functions should also compare equal across translation units
- * regardless of whether they are declared inline.
- *
- * The above requirements mean that the declaration and definition of non-trivial
- * inline functions must be separated so that the definitions will only
- * appear when necessary. In addition, three different linkage models need
- * to be supported:
- *
- *  - The C99 model, where a standalone function is emitted only if there is any
- *    `extern inline` or non-`inline` declaration (including the definition itself)
- *
- *  - The GNU model, where an `inline` definition emits a standalone function and an
- *    `extern inline` definition does not, regardless of other declarations
- *
- *  - The C++ model, where `inline` emits a standalone function with special
- *    (COMDAT) linkage
- *
- * The macros below wrap up everything above. All inline functions defined in header
- * files have a single non-inline definition emitted in the compilation of
- * mpack-platform.c. All inline declarations and definitions use the same MPACK_INLINE
- * specification to simplify the rules on when standalone functions are emitted.
- * Inline functions in source files are defined MPACK_STATIC_INLINE.
- *
- * Additional reading:
- *     http://www.greenend.org.uk/rjk/tech/inline.html

- * Here we define mpack_assert() and mpack_break(). They both work like a normal

- * you can safely resume execution from mpack_break(), whereas mpack_assert() is
- * always fatal.
- *
- * In release mode, mpack_assert() is converted to an assurance to the compiler
- * that the expression cannot be false (via e.g. __assume() or __builtin_unreachable())
- * to improve optimization where supported. There is thus no point in "safely" handling
- * the case of this being false. Writing mpack_assert(0) rarely makes sense (except
- * possibly as a default handler in a switch) since the compiler will throw away any
- * code after it. If at any time an mpack_assert() is not true, the behaviour is
- * undefined. This also means the expression is evaluated even in release.
- *
- * mpack_break() on the other hand is compiled to nothing in release. It is
- * used in situations where we want to highlight a programming error as early as
- * possible (in the debugger), but we still handle the situation safely if it
- * happens in release to avoid producing incorrect results (such as in
- * MPACK_WRITE_TRACKING.) It does not take an expression to test because it
- * belongs in a safe-handling block after its failing condition has been tested.
- *
- * If stdio is available, we can add a format string describing the error, and
- * on some compilers we can declare it noreturn to get correct results from static
- * analysis tools. Note that the format string and arguments are not evaluated unless
- * the assertion is hit.
- *
- * Note that any arguments to mpack_assert() beyond the first are only evaluated
- * if the expression is false (and are never evaluated in release.)
- *
- * mpack_assert_fail() and mpack_break_hit() are defined separately
- * because assert is noreturn and break isn't. This distinction is very
- * important for static analysis tools to give correct results.
