Function RM_ZsetFirstInLexRange

app/redis-6.2.6/src/module.c:2880–2882

Setup a sorted set iterator seeking the first element in the specified * lexicographical range. Returns REDISMODULE_OK if the iterator was correctly * initialized otherwise REDISMODULE_ERR is returned in the * following conditions: * * 1. The value stored at key is not a sorted set or the key is empty. * 2. The lexicographical range 'min' and 'max' format is invalid. * * 'min' and 'max' sh

 * The function does not take ownership of the objects, so they can be released
 * ASAP after the iterator is setup. */

/* Exactly like RedisModule_ZsetFirstInLexRange() but the last element of
 * the range is selected for the start of the iteration instead. */
