* @type array $role__in An array of role names. Matched users must have at least one of these
* roles. Default empty array.
* @type array $role__not_in An array of role names to exclude. Users matching one or more of these

* @type string $meta_key User meta key. Default empty.
* @type string $meta_value User meta value. Default empty.
* @type string $meta_compare Comparison operator to test the `$meta_value`. Accepts '=', '!=',
* '>', '>=', '<', '<=', 'LIKE', 'NOT LIKE', 'IN', 'NOT IN',
* 'BETWEEN', 'NOT BETWEEN', 'EXISTS', 'NOT EXISTS', 'REGEXP',
* 'NOT REGEXP', or 'RLIKE'. Default '='.
* @type array $include An array of user IDs to include. Default empty array.
* @type array $exclude An array of user IDs to exclude. Default empty array.
* @type string $search Search keyword. Searches for possible string matches on columns.
* When `$search_columns` is left empty, it tries to determine which
* column to search in based on search string. Default empty.
* @type array $search_columns Array of column names to be searched. Accepts 'ID', 'login',
* 'nicename', 'email', 'url'. Default empty array.
* @type string|array $orderby Field(s) to sort the retrieved users by. May be a single value,
* an array of values, or a multi-dimensional array with fields as
* keys and orders ('ASC' or 'DESC') as values. Accepted values are
* 'ID', 'display_name' (or 'name'), 'include', 'user_login'

* (or 'email'), 'user_url' (or 'url'), 'user_registered'

* the value of `$meta_key`, or an array key of `$meta_query`. To use
* 'meta_value' or 'meta_value_num', `$meta_key` must be also be
* defined. Default 'user_login'.
* @type string $order Designates ascending or descending order of users. Order values
* passed as part of an `$orderby` array take precedence over this
* parameter. Accepts 'ASC', 'DESC'. Default 'ASC'.
* @type int $offset Number of users to offset in retrieved results. Can be used in
* conjunction with pagination. Default 0.
* @type int $number Number of users to limit the query for. Can be used in
* conjunction with pagination. Value -1 (all) is supported, but
* should be used with caution on larger sites.
* Default empty (all users).
* @type int $paged When used with number, defines the page of results to return.
* Default 1.
* @type bool $count_total Whether to count the total number of users found. If pagination
* is not needed, setting this to false can improve performance.
* Default true.
* @type string|array $fields Which fields to return. Single or all fields (string), or array
* of fields. Accepts 'ID', 'display_name', 'user_login',
* 'user_nicename', 'user_email', 'user_url', 'user_registered'.
* Use 'all' for all fields and 'all_with_meta' to include
* meta fields. Default 'all'.
* @type string $who Type of users to query. Accepts 'authors'.
* Default empty (all users).
* @type bool|array $has_published_posts Pass an array of post types to filter results to users who have
