GetRankList
public BackendReturnObject GetRankList(string rankUuid);
public BackendReturnObject GetRankList(string rankUuid, int limit);
public BackendReturnObject GetRankList(string rankUuid, int limit, int offset);
The URank ranking method can only look up NULL groups in grouped leaderboards.
If you want to check leaderboards according to groups, use the Leaderboard method. 
Parameters
| Value | Type | Description | Default | 
|---|---|---|---|
| rankUuid | string | uuid of the ranking to look up | - | 
| limit | int | Number of guilds to look up (1 - 50) | 10 | 
| offset | int | Starting point of the ranking to look up (0 or more) | 0 | 
The rankUuid value can be checked using the following methods:
- Create a ranking in BACKND Console and check the uuid value from the information of the ranking
 - Check the uuid value using the Look up ranking information of all guilds method
 
Description
Looks up list of guilds registered in the ranking using a uuid value.
Example
Synchronous
// Look up the 1st - 10th guilds in the rankUuid ranking
Backend.URank.Guild.GetRankList("rankUuid");
// Look up the 1st - 100th guilds in the rankUuid ranking
Backend.URank.Guild.GetRankList("rankUuid", 100);
// Look up the 11th - 20th guilds in the rankUuid ranking
Backend.URank.Guild.GetRankList("rankUuid", 10, 10);
Asynchronous
// Look up the 1st - 10th guilds in the rankUuid ranking
Backend.URank.Guild.GetRankList("rankUuid", callback=> {
    // Post-process
});
// Look up the 1st - 100th guilds in the rankUuid ranking
Backend.URank.Guild.GetRankList("rankUuid", 100, callback=> {
    // Post-process
});
// Look up the 11th - 20th guilds in the rankUuid ranking
Backend.URank.Guild.GetRankList("rankUuid", 10, 10, callback=> {
    // Post-process
});
SendQueue
// Look up the 1st - 10th guilds in the rankUuid ranking
SendQueue.Enqueue(Backend.URank.Guild.GetRankList, "rankUuid", callback=> {
    // Post-process
});
// Look up the 1st - 100th guilds in the rankUuid ranking
SendQueue.Enqueue(Backend.URank.Guild.GetRankList, "rankUuid", 100, callback=> {
    // Post-process
});
// Look up the 11th - 20th guilds in the rankUuid ranking
SendQueue.Enqueue(Backend.URank.Guild.GetRankList, "rankUuid", 10, 10, callback=> {
    // Post-process
});
