Some functions provide a \c noexcept guarantee, if the compiler supports it.
|
|
In these cases, the \ref RAPIDJSON_ASSERT macro cannot be overridden to
|
|
throw an exception. This macro adds a separate customization point for
|
|
such cases.
|
|
|
|
Defaults to C \c assert() (as \ref RAPIDJSON_ASSERT), if \c noexcept is
|
|
supported, and to \ref RAPIDJSON_ASSERT otherwise.
