Detailed Description

const struct e4c_exception_type NOT_ENOUGH_MEMORY = {NULL, "Not enough memory"};
const struct e4c_exception_type TIMED_OUT = {NULL, "Timed out"};
 
/* Base exception for all pet-related errors */
const struct e4c_exception_type PET_ERROR = {NULL, "Pet error"};
 
/* Specific types of pet errors */
const struct e4c_exception_type PET_NOT_FOUND = {&PET_ERROR, "Pet not found"};
const struct e4c_exception_type PET_STORE_CLOSED = {&PET_ERROR, "Pet store closed"};
