Returns the position of an element in a sorted set, with scores in descending order. The index returned is 0-based (the lowest score member has an index of 0).

[Redis documentation]

Arguments #

zrevrank(key, member, [options]);

Arguments	Type	Description
`key`	string	Sorted set key
`member`	string	Member value
`options`	object	Optional query arguments

options #

The options arguments can contain the following option properties:

Property	Type (default)	Description
`queuable`	boolean (true)	If `true`, queues the request during downtime, until connected to Kuzzle again
`timeout`	number (`-1`)	Time (in ms) during which a request will still be waited to be resolved. Set it `-1` if you want to wait indefinitely
`triggerEvents`	boolean (`false`)	If set to `true`, will trigger events even if using Embeded SDK. You should always ensure that your events/pipes does not create an infinite loop. Available since Kuzzle 2.31.0

Resolve #

Resolves to the index of the found member in the sorted set, or to null if the member is not found.

Usage #

try {
  await kuzzle.ms.zadd('ssetfoo', [
    {member: 'foo', score: '42'},
    {member: 'bar', score: '4'},
    {member: 'baz', score: '-272.15'}
  ]);
  // Prints: 0
  console.log(await kuzzle.ms.zrevrank('ssetfoo', 'foo'));
