-/* Decode the next character, c, from buf, reporting errors in e.
- *
- * Since this is a branchless decoder, four bytes will be read from the
- * buffer regardless of the actual length of the next character. This
- * means the buffer _must_ have at least three bytes of zero padding
- * following the end of the data stream.
- *
- * Errors are reported in e, which will be non-zero if the parsed
- * character was somehow invalid: invalid byte sequence, non-canonical
- * encoding, or a surrogate half.
- *
- * The function returns a pointer to the next character. When an error
- * occurs, this pointer will be a guess that depends on the particular
- * error, but it will always advance at least one byte.

- \rst
- A dynamically growing memory buffer for trivially copyable/constructible types
- with the first ``SIZE`` elements stored in the object itself.
-
- You can use one of the following type aliases for common character types:
-
- +----------------+------------------------------+
- | Type | Definition |
- +================+==============================+
- | memory_buffer | basic_memory_buffer<char> |
- +----------------+------------------------------+
- | wmemory_buffer | basic_memory_buffer<wchar_t> |
- +----------------+------------------------------+
-
- **Example**::
-
- fmt::memory_buffer out;
- format_to(out, "The answer is {}.", 42);
-
- This will append the following output to the ``out`` object:
-
- .. code-block:: none
-
- The answer is 42.
-
- The output can be converted to an ``std::string`` with ``to_string(out)``.
