* @brief Exception error codes possible for dpp::exception::code()
|
|
*
|
|
* This list is a combined list of Discord's error codes, HTTP error codes,
|
|
* zlib, opus, sodium and C library codes (e.g. DNS, socket etc). You may
|
|
* use these to easily identify a type of exception without having to resort
|
|
* to string comparison against dpp::exception::what()
|
|
*
|
|
* For detailed descriptions of each error code, see the text description
|
|
* returned in `what()`.
|
|
*
|
|
* @note Some exceptions MAY have error codes which are NOT in this list
|
|
* in the event a C library is updated and adds new codes we did not document
|
|
* here. In this case, or where the code is not specific, refer to `what()`.
