ARRAY ELEMENT KEY BUILDING

       When  writing  marshaling  layers  between  higher  level  languages and Libbson, you will
       eventually need to build keys for array elements. Each element  in  a  BSON  array  has  a
       monotonic string key like 0 , 1 , etc. Using snprintf(3) and others tend to be rather slow
       on most libc implementations.  Therefore,  Libbson  provides  bson_uint32_to_string(3)  to
       improve this. Using this function allows an internal fast path to be used for numbers less
       than 1000 which is the vast majority of arrays. If the key is larger than that, a fallback
       of snprintf(3) will be used.

       For more information, see bson_uint32_to_string(3) \&.
